Técnicas algorítmicas de búsqueda multimedia y multilingüe para localizar personas en contenidos audiovisuales

Published on 2 March, 2017

El proyecto, financiado por el Mineco, arrancó hace un año y cuenta con 70.000 euros de presupuesto

El Grupo de Tecnologías Multimedia trabaja en procesamento de habla y de imagen

El Grupo de Tecnologías Multimedia trabaja desde hay un año en el proyecto TraceThem, una investigación en técnicas algorítmicas de búsqueda multimedia y multilingüe para localizar personas en contenidos audiovisuales. Se trata de un proyecto financiado polo Programa Estatal de Fomento de la I+D+i de Excelencia con un presupuesto de 70.000 euros y en el que están involucrados los miembros de GTM Carmen García Mateo, José Luis Alba Castro, Antonio Cardenal, Eduardo Rodríguez Banga, Laura Docío, Carmen Magariños y Paula López, grupo que forma parte del centro de investigación AtlantTIC.

Equipo GTM

Equipo GTM

El proyecto, de tres años de duración, arrancó en enero de 2016 y tiene como objetivo desarrollar y mejorar técnicas para la búsqueda de información sobre personas que aparecen en grabaciones audiovisuales, por lo que las tecnologías básicas que emplean los investigadores son el procesamiento de habla y de imagen, como explica García Mateo, directora del GTM. La necesidad de avanzar en este campo responde a la multiplicación de contenidos audiovisuales y nuevos escenarios como MOOCs, videoblogs, tutoriales, etc. que se unen a los contenidos tradicionales como televisión, noticias o películas. Ante esta cantidad de información, la automatización del proceso de búsqueda para filtrar, acceder y seleccionar los contenidos se convierte en un aspecto clave. Así, TraceThem tiene como finalidad, destaca el profesor José Luis Alba, “desarrollar una tecnología que evite el indexado manual de los contenidos y permita buscar directamente lo que interesa a través del procesado de vídeo y audio”. Estos avances son de especial utilidad para la indexación de contenidos multimedia para grandes repositorios, como por ejemplo de medios de comunicación e instituciones educativas. El objetivo final es tener un motor de indexación que permita localizar contenidos o personas en esos vídeos y audios y “el techo de este tipo de investigación sería conseguir que motores de búsqueda de internet como Google encontrasen no sólo texto, sino audio y vídeo sin necesidad de que esos contenidos fuesen indexados manualmente, como se hace ahora”.

Búsqueda de personas y voces

La catedrática Carmen García Mateo explica que la información que se pretende extraer con estas tecnologías “está siempre dentro de un contexto comunicativo, es decir, son contenidos de alguien y para alguien, por lo que la caracterización de las personas involucradas en este contexto juega un papel central”. Se enfocan de este modo a encontrar información sobre las personas y su forma de interactuar: quiénes son, qué dicen, cómo se comunican, que están haciendo… es decir, el interés está en descubrir personas y contenido. La extracción de información relacionada con las personas se lleva a cabo a través de procesamiento de audio, procesamiento de vídeo y procesamiento combinado de audio y vídeo. Para esto, los investigadores trabajan en el análisis de contenido multimedia, biometría de voz y cara, segmentación de audio y diarización de hablantes, detección del estado emocional y detección de personas que interactúan.

Las competiciones como herramienta de I+D

La finalidad de este proyecto no es desarrollar aplicaciones comercializables, sino mejorar la tecnología, y uno de los instrumentos para testar y validar los avances son las competiciones internacionales en las que participan diferentes grupos de universidades y centros tecnológicos. Estos concursos establecen marcos experimentales comunes para mejorar la tecnología pero también para potenciar la colaboración con otros grupos, ayudando a descubrir las fortalezas y debilidades de los algoritmos y sistemas desarrollados. En 2016, las ingenieras viguesas participaron en dos competiciones: Mediaeval (Holanda) y Albayzin Evaluation (Portugal). En el primero, como explican Laura Docío y Paula López, trabajamos con un “conjunto grande de vídeos en el que tuvimos que descubrir la identidad de la persona que aparece en un extracto de unos segundos de duración empleando sólo información obtenida del texto, voz y vídeo”, mientras que Albayzin 2016 se centra en la búsqueda de voz. Los resultados respaldan el trabajo del grupo, ya que en Mediaeval consiguieron un 4º puesto y en Albayzin obtuvieron el 1º puesto en la búsqueda de palabras en grabaciones de voz y el 3º en diarización, es decir, en la identificación de los turnos de los distintos locutores de un audio.

El desafío: sistemas fuertes que funcionen en condiciones adversas

Los investigadores de GTM llevan trabajando en este campo durante años y este no es el primero proyecto que desarrollan en este campo. Explican que algunas innovaciones ya se comercializan y funcionan razonablemente bien en entornos controlados, pero “cuando las condiciones no son las excelentes, como por ejemplo incorporando ruido, la presencia de distintos idiomas, las referencias cruzadas, etc. no trabajan tan bien. Por lo tanto, el desafío es hacer estos sistemas fuertes la condiciones acústicas adversas”. Además, el procesamiento de estos documentos multimedia implica la dificultad añadida de que los contenidos pueden aparecer en diferentes idiomas, lo que representa un mayor desafío tecnológico, ya que se necesitan herramientas adaptadas a las diferentes lenguas.

Otras líneas de investigación dentro del proyecto

Dentro del proyecto TraceThem, los investigadores desarrollan también otras dos líneas de trabajo paralelas. Una de ellas es la de identificación de locutor, que permite transformar una voz de forma que no se sepa cuál es el emisor de origen y que tiene especial importancia para mantener la privacidad en las bases de datos de voz. “No se trata de distorsionar”, explican, “queremos que suene igual de natural que el original, pero con otra voz”. Otra línea de trabajo es la adaptación de locutor cross-lingual, que se centra en desarrollar técnicas que permitan llevar la identidad de una voz a otra, entre un par de lenguas distintas, es decir, se trata de producir voz de un mismo locutor pero en otro idioma, algo que tendría una posible aplicación para los traductores automáticos, para que la voz del emisor suene en otro idioma igual que en el original.

AtlantTIC gets 1.2 million euros for its research excellence

Published on 9 December, 2016

AtlantTIC se confirma como agrupación estratégica consolidada

Por su parte, Cinbio y Océano.-Ecimat logran la acreditación de centros de investigación singulares

La Universidad de Vigo ha conseguido más de 4,7 millones de euros en la convocatoria de ayudas para la acreditación, estructuración y avance de los centros de investigación singulares y agrupaciones estratégicas consolidadas del Sistema Universitario de Galicia. La resolución de la Consellería de Cultura, Educación y Ordenación Universitaria, resuelve la concesión de 1,2 millones de euros en el caso de AtlantTIC como agrupación estratégica consolidada; y de 1,7 millones de euros, respectivamente, para el Centro de Investigaciones Biomédicas, Cinbio, y para Océano-Ecimat, en la modalidad de centros singulares de investigación.

Del los 13,2 millones de euros que la Xunta concede en esta convocatoria a centros y agrupaciones singulares de las tres universidades gallegas, la Universidad de Vigo ha obtenido algo más del 35% del total de las ayudas, que se prolongarán durante cuatro anualidades, desde 2016 a 2019. La convocatoria impulsada por la Consellería de Educación con el objetivo de reconocer la excelencia investigadora de centros y agrupaciones estratégicas está financiada en un 80% por el Fondo Europeo de Desarrollo Regional (FEDER).

Un paso adelante para AtlantTIC
Desde AtlantTIC, el catedrático Carlos Mosquera aclara que llevan recibiendo este tipo de ayudas desde su creación. “La primera vez que la Xunta las sacó fue en el 2006 y, desde entonces, siempre nos hemos beneficiado de ellas, si bien AtlantTIC no se constituyó como tal hasta 2011″, subrayó el investigador, que resaltó también el “juego” que acercan las agrupaciones estratégicas para fomentar la labor investigadora en la Universidad. “En este caso, además, hablamos del desarrollo de sectores tan estratégicos para Vigo como son las ciencias de la vida, en el sentido más amplio, y las telecomunicacións”, apuntó Mosquera.

Respecto a la renovación de la ayuda, Mosquera considera que se trata de “seguir en la carrera, pero para nosotros no es suficiente, el importante es seguir trabajando y aspirando a más, pues el objetivo es ser un centro de investigación de referencia, no sólo a nivel gallego, y para lograrlo hay que trabajar mucho”, recalcó el investigador, que insistió en que “esta ayuda es la gasolina para seguir tirando, pero necesitamos mucho más”.

Professor Ramón Hermida, fellow of the American Society of Hypertension

Published on 25 October, 2016

He is the first and only non-American member who becomes part of this prestigious group

With his team in the Bioengineering and Chronobiology Laboratory, they have developed pioneering research in the field of chronobiology of hypertension

 

Professor of Signal Theory and Communications in the University of Vigo and author of more than 275 research papers, Ramón C. Hermida has given 253 invited lectures and about 2200 papers at national and international conferences; this year he has become fellow member of the American Society of Hypertension, a distinction reserved only for the most prominent members as a recognition from the international community to professional achievements and research work.

This appointment, the first and only given to a non-American ASH member, comes after more than 30 years in applied research in the area of telecommunications, specifically in the field of biomedical engineering and chronobiology, areas of expertise of Hermida. Currently, he develops its research activity in the Bioengineering and Chronobiology Laboratory (LBC), within the Research Center AtlantTIC. As Hermida says, “it is an honour for me and for the group as it is a recognition to our experience and research lines we’re working in”.

Prof. Ramón Hermida

Prof. Ramón Hermida

Educated in Spain and United States, professor Hermida is at this moment president of the International Society for Chronobiology and of ‘Sociedad Española de Cronobiología Aplicada, Cronoterapia y Riesgo Vascular’. From Bioengineering and Chronobiology Laboratory, he has directed/leaded more than 70 research projects and clinical trials in ambulatory monitoring of blood pressure and hypertension chronotherapy; in the field of gynecology and obstetrics, in early identification and prevention of preeclampsia; or in oncology, through ovarian and bladder cancer chronotherapy studies, the chronoepidemiology or prevention of breast cancer.

Hygia network

Results derived from Hygia Project have revolutionized vascular medicine globally, as it has been the first study in the world that has been able to confirm that cardiovascular risk of a patient can only be properly determined by measuring blood pressure during sleep. As Hermida explains “Hygia is the first study to confirm that the risk of a cardiovascular event is primarily associated with the progressive rise of blood pressure during rest and not during the hours of activity, as it has been diagnosed in recent decades; that’s why it is vital the prognostic value of ambulatory blood pressure monitoring (ABPM)”.

Hygia was born within the University of Vigo as a research project parallel to the welfare work, paying special attention to continuing medical education.

After more than 9 years of study, Hygia has become a professional network fully integrated in Galician health system, in which 292 researchers are involved and more than 20,000 patients have been monitored to extend the use of ABPM in primary care for hypertension diagnosis.

The select FASH club

Becoming FASH (Fellow of American Society of Hypertension) is not a simple process. Every year, the American Society of Hypertension (ASH) proposes a list with the names of experts and researchers whose work is the most relevant worldwide and most deserving of becoming fellow, based on the recommendations other fellow members must provide.  This is a recognition of the work done, both clinical and research contribution in the field of hypertension and cardiovascular risk; as well as in the area of teaching and knowledge transfer.

In this case, the ASH has highlighted two merits achieved by Prof. Hermida and his team from Bioengineering and Chronobiology Laboratory. On the one hand, ASH positions them like the fathers of chronobiology of hypertension worldwide because, in Hermida’s own words, “we have opened up an unknown area so far and, at present, the fact that hypertensive medication is more favourable at night is already in the most important clinical practice guidelines”. Thus, the conclusions of Hygia project are in the clinical practice guideline of the American Diabetes Association, the European Society of Cardiology or the Japanese Society of Hypertension, to name but a few.

Recently, the US Preventive Services Task Force, a committee of experts for public health issues of the US government, has resolved for the first time in history that the diagnosis of hypertension in adults over the age of 18 must be always and necessarily done with ambulatory monitoring, endorsing the conclusions of Hygia Project. Those recommendations are based mainly on the findings of 5 research studies in the area of cardiovascular risk published in the last 25 years and considered by the panel of experts as the most relevant and reliable, one of them is a previous study of Prof. Hermida’s group.

Carmen Garcia-Mateo highlights the need to promote the empowerment of women and young people

Published on 20 July, 2016

In 2014 she got “María Josefa Wonenburger” Award, given by Xunta de Galicia

She has just been named plenary member by election of Galician Culture Council

 

Stablished in School of Telecommunication Engineering in the University of Vigo since the late 1980s, Carmen Garcia-Mateo has given her life to teaching and research activity. “When we started, despite the roughness because we were starting our career and it was necessary to coordinate teaching, research, contacts with companies, the setting up of laboratories… and our own training; it was a very intense, but also a satisfying time”. 30 years later, Garcia-Mateo keeps on working as a Professor in the department of Signal Theory and Communications and as the director of Multimedia Technology Group (GTM) in AtlantTIC Research Center.

carmengarcia

“From GTM we have always bet on collaborative research, with our presence on international networks; and with a clear mobility vocation, so that we could get in touch into another universities and centers, allowing us to grow up in knowledge and to improve our research quality”, points Garcia-Mateo. Recognised as a Competitive Reference Group by Xunta de Galicia (Galician Regional Government) since 2004, GTM focuses the research lines on conversion text-voice (TTS) and multilingual automatic voice recognition (ASR) in Galician, Spanish and English; another active work line, and thanks to which the group has already got international awards and recognitions, such as the 4th place in MediaEval 2015, a benchmarking contest about multimedia evaluation and data recovery. GTM also works on applied research on analysis and facial recognition based on biometrics especially for the internet.

Nowadays, Garcia-Mateo and her team work to ensure the visibility and the importance of Galician Innovation System, through their research. Leaders on multilingual people information detection (voice and image) on multimedia files, since 2004 GTM is part of European excellence Network Biometrics for Secure Authentication – BIOSECURE, becoming a referent on people metadata extraction on audiovisual recordings.

A model for every woman

In 2014 Garcia-Mateo received the “Maria Josefa Wonenburger” award, a prize created in 2006 by Xunta de Galicia in order to “highlight the most relevant women careers in science and technology”. As Garcia-Mateo explains “today, only 20% of students in telecommunication engineering are women, when 15 years ago they became almost 40%. It is essential for us to make the younger know the practical application of technological studies, for both women and men”.

During 2016 Secretaría Xeral de Igualdade (Galician Regional Office for Gender Equality) has organised a travelling exhibition that reflects the career of the Wonenburger awarded, women who broke down stereotypes and now became role models for the youngest. The exhibition is composed by 11 big panels, with the awarded bios and it has been located in the seven campus of the three Galician Universities to give more visibility these figures: relevant women in science, research and technology areas. Garcia-Mateo says that “there is still a long way to go” to put the presence of women in scientific and technological field on the same level and notes that “these initiatives help to make visible our activity. It is a new step to make other people, especially younger ones, to know what we can do”.

Work for Galician culture and language

Being aware of the importance of a language and the need to pass it on, Garcia-Mateo has been working from the beginning in the research of multilingual speech technologies, setting Galician at the same level as other languages like Spanish or English, and its use in digital and multimedia environments. Therefore, after a career full of successes and dedicated to the dissemination of technology and Galician language and culture, Garcia-Mateo has received “with great pride and enthusiasm” her appointment as plenary member of Consello da Cultura Galega (Galician Culture Council). “At a personal level, it is a very enriching experience. This appointment will allow me to develop projects with other members of Consello, joining my experience and the knowledge to others’ expertise, everything to support and promote Galician culture”.

IH&MMSec has been held at Vigo from June 20th to 22nd, and has the support of Xunta de Galicia (Galician Government), University of Vigo, Ayuntamiento de Vigo and Fundación Empresa Universidad (FEUGA); so that the implication of technology and research centers AtlantTIC, Gradiant, CNRS and CRIStAL; and the supporting companies Amped Software, Intel y Atos; and the H202 European research project WITDOM.

21 selected papers from 61 submissions from five continents

In recent years, hiding information and multimedia security research has been growing in maturity and recognition. More and more companies and people are now aware of the big amount of sensitive information available in the web and the need to protect that data.

IH&MMSec 2016 edition has received 61 submissions of researchers from five continents, highlighting countries like the United States, China, France and Germany. However, only 21 papers have been selected to be presented during the technical sessions; “only an acceptance rate of 36%, which shows our intention to preserve IH&MMSec as one of the premier conferences in this field”, explains Pérez González.

More than 50 researchers from Spain, France, Germany, Austria, Italy, UK, USA, Canada, China, South Korea and Japan will take part in this event, which will be represented universities of Oxford, Lille, New Jersey, Innsbruck, Trento, Macao, Tsukuba, Ottawa and Salzburg, among others; research centers (CNRS, INRIA, Fraunhofer, AtlantTIC and Gradiant); and companies such as Atos, Amped Software or Morpho.

Plenary sessions: Battista Biggio and Martino Jerian

During the conference, two international experts bring their knowledge to attendees, both the academic point of view and the experience from business. On the one hand, Battista Biggio, renowned researcher at the University of Cagliary and co-founder of the company Pluribus One, expert in machine learning and computer security, will talk about Machine Learning under Attack: Vulnerability Exploitation and Security Measures. Martino Jerian, CEO and founder of Amped Software, multimedia forensics expert, will give a talk entitled Bringing Multimedia Security from the Research Lab to the Forensics Lab.

Martino Jerian

Martino Jerian

The two guest speakers highlighted the importance of such international conferences where both, researchers and companies, converge. Martino Jerian recognizes its usefulness for companies to maintain contact with the R&D environment allowing “create networks, open new avenues of research, meet people, etc.” and recalls that “we cannot have final products without research, and research without practical development will never reach the hands of users”. Battista Biggio, meanwhile, emphasizes that the realization of workshops like IH&MMSec is also important to raise awareness about the risks in multimedia security and for companies and institutions to achieve progress and make systems more secure, “which is the ultimate goal”.

Battista Biggio

Battista Biggio

On multimedia security challenges, Martino Jerian points to the multimedia authentication, a topic still poorly developed but that seems to have great potential. Battista Biggio works on secure machine learning, a field where “care should be taken” to ensure the protection of multimedia images “allowing automatic detection of modified or counterfeit images”. Both, from its company and from the University of Cagliari, Battista Biggio works mainly in computer security, and stressed that “there are a lot of threats for people who are using smart devices and social media, we have a wide range of services that take advantage of these intelligent machines, with an algorithm that analyses what we are doing”. So “on the one hand, this technology makes our life easier, because we have a lot of services; but on the other, this has generated many threats, many cybercriminals can exploit these technologies to make money, and from a criminal point of view, are exploiting our privacy and our security”.

Premios y novedades

Con el objetivo de recompensar la labor de investigación de los jóvenes con mayor potencial y proyección en el área de Information Hiding and Multimedia Security, IH&MMSec 2016 entregará dos premios a los mejores trabajos de investigación de estudiantes. Los galardones constan de un diploma acreditativo y 500 euros en metálico.

Además, este año “tendrá lugar por primera vez una sesión de ‘trabajo en curso’, que se celebrará el primer día, y en la que se presentarán trabajos aún no publicados”, explica Pérez González, que considera esta iniciativa “muy positiva” porque favorecerá la creación de alianzas y la posibilidad de recibir realimentación de los participantes sobre investigaciones que aún no han visto la luz.

Awards and news

In order to reward the research of young people with the greatest potential and projection in the area of Information Hiding and Multimedia Security, IH&MMSec 2016 deliver two awards for the best student research work. The awards consist of a diploma and 500 euros in cash.

In addition, this year “will take place for the first time a session of ‘work in progress’ to be held on the first day, and where work still unpublished will be presented”, says Perez-González, who considers this one a “very positive” initiative because it will encourage the creation of partnerships and the opportunity to receive feedback from participants on not published investigations.

AtlantTIC researchers develop an encryption system to ensure data privacy processed in the cloud

Published on 27 April, 2016

This encryption system guarantees privacy from origin to end and allows us to work directly on encrypted data

Signal Processing Encryption Domain is a new field of research responsible for full protection of sensitive data, ensuring privacy and confidentiality in outsourced and distributed services 

 

In the last decade, we have witnessed the transformation in the way to communicate each other and, consequently, it has also changed the control in our personal information kept and available in the internet. Researchers from the Signal Processing in Communications group (GPSC) in AtlantTIC Research Center have been working for more than 10 years in signal processing encryption domain (SPED) with the main purpose of “protecting the data and guaranteeing privacy and confidentiality for both home and business users”, explains Juan Ramón Troncoso, main researcher and expert in privacy and security in the team run by Professor Fernando Pérez González.

Juan Ramón Troncoso,  AtlantTIC researcher and  expert in privacy and security

Juan Ramón Troncoso, AtlantTIC researcher and expert in privacy and security

To achieve this goal, engineers from GPSC have developed a sort of advanced tools on homomorphic cryptography and secure signal processing to give completely private and trusted services from origin to end, with no access for those who intervene in data processing. This technology, that has been applied to multimedia signal processing (audio, video, biometrics, genetic data, DNA, etc.), allows to work in a “blind” way on encrypted communications, without knowing their content. In a traditional communication channel encoding (such as end-to-end encryption) is not possible to see the content, it is not possible to modify it or process it either; nevertheless, thanks to encryption strategies developed in GPSC it is, in such a way that “the server can work on data without decoding, knowing and coding it again” clarifies Troncoso, making cloud services possible with full confidentiality and privacy for users, who knows that not even the provider has access to their data.

Despite this is a recent research area, AtlantTIC team has develop a toolbox that uses their own encrypted scheme and can encrypt any kind of multidimensional signs (audio – WAV–, images –JPEG, GIF, PNG–, video, 4D ultrasounds, etc.) compactly and process them efficiently in the encrypted domain. The SPED bookcase GPSC group has developed are responsible for processing every single encoded file, making possible to do several operations such as filters, enhancement of edges, search interest image areas, etc.; this system may offer a full secure and confidential cloud service completely transparent for the users, avoiding the need to have specific hardware.

Security, privacy and confidentiality are guarantees 

In the last few years, regulatory frameworks in Spain and, especially in the EU, have taken advanced to give more guarantees in personal data protection at any context; however, that advances do not mean that applications we daily use implement appropriate technological mechanisms to ensure our security and preserve our privacy, especially with the fast evolution of the Internet of Things and connected households.

An example of effects in citizen awareness-raising about their rights in data protection and privacy is the recent end-to-end encryption for all their communications in a very famous instant messaging network. Nevertheless, the technologies available nowadays used by these products are usually insufficient in order to give people a wide range of fully confidential services and, in best cases, are limited to protect exclusively their communications. The research developed in AtlantTIC goes further, as Troncoso shows “this kind of advanced cryptographic tools are much more versatile and flexible, allowing people to protect their sensitive data not only in their communications and storage, but also along/over the process, that is it may work on data without having access to their content, so privacy is guarantee even against the service provider”.

Cloud data privacy

Cloud data privacy

The development of these kind of tools makes a great step in privacy and confidentiality research, since data use is completely secure and avoid the user to trust in service provider, who cannot access the information but who can work on it. These techniques make possible secure processing a big amount of extremely sensitive information, such as genomic and medical data or economic and financial information.

Táctica, applied R&D ICT project

The development of these advanced cryptographic tools, so does other privacy protection technologies, has been done thanks potential of Táctica Project, R&D project focus on ICT and carried out inside  School of Telecommunications Engineering from the University of Vigo. This research has had the support of Spanish Government, Ministerio de Economía y Competitividad (MINECO); and EU, Fondo Europeo de Desarrollo Regional (FEDER).

TACTICA has allowed to invest more than 8M€ in applied R&D made in Galicia Region (in the northwest of Spain), and has focused the research in 5 basic areas: advanced software architectures (cloud computing and cloud multimedia systems, specifically telemedicine); multimedia technologies (semantics indexing and search, big data and opinion analysis); wireless communications (satellite transmissions systems, SDR and SDN); security (processing in the encrypted domain, multimedia forensics, privacy technologies); and measurement and characterization (material characterization and polarimetric radar).
