Campagnes d'évaluation et compétitions

 

TRECVID 2009 et TRECVID 2011

Résumé : Ces évaluations comparent les algorithmes de détection de copie développés par différents laboratoires à travers le monde. L’objectif est de détecter les vidéos qui sont une copie d’une œuvre originale, en utilisant l’audio, la vidéo ou la combinaison des deux. 

Résultat : Nous avons développé une approche particulièrement efficace pour la détection de copies, et elle s’applique aussi bien à l’audio qu’à la vidéo. Les algorithmes développés au CRIM se sont avérés les plus performants quant au degré de détection et à la vitesse d’exécution pour TRECVID 2009 et ont obtenu le 2e meilleur résultat dans TRECVID 2011.

Évaluation SRE du NIST 2006, 2008, 2010, 2012, 2016

 

Résumé : Cette campagne évalue les systèmes de vérification de l’identité d’une personne à partir de la voix développés par différents laboratoires à travers le monde.

Résultat : Nos algorithmes ont obtenu des résultats parmi les meilleurs dès la première année. Leur influence sur la communauté s’est manifesté dès la deuxième année de participation par des changements au paradigme de test et l’adoption de l’analyse factorielle, des i-vectors et de l'analyse probabiliste linéaire discriminative par tous les laboratoires les plus performants. 

ETAPE 2011 [2011-12]

Résumé : Cette campagne d’évaluation est la suite des évaluations précédentes ESTER qui portaient sur des émissions de radio et de télévision françaises. Dans ETAPE, les émissions ont été spécialement choisies pour comporter une plus grande part de recouvrement dans les tours de parole (lors de débats, entre autres). 

Résultat : Nous avons pu comparer nos systèmes avec ceux d’une dizaine de laboratoires français, sur une base de données commune avec une évaluation indépendante selon une méthodologie identique, et constater qu’ils se situent encore parmi les meilleurs au monde.

Projets de R-D

 

Accès-VD, Experimental service of video description broadcasting for DVD content

Summary:  The Accès-VD project aims at perfecting and studying the usability of a DVD player developed by our team that allows blind and visually impaired individuals to access the content of any DVD that does not contain a video description soundtrack. It is offered on a computer and uses a synchronization technology that in no way modifies the visual or acoustic content of the raw DVD. 

Partner: This project was financed in part by the Office des Personnes Handicapées du Québec (OPHQ).

Audio-video fusion for speech recognition

Summary: This research project aimed at exploring how to approach the problem of audio and video fusion in the case of recognizing French Québécois speech in the context of prepared newscasts. The project also aimed at developing a test bed for the extraction of audio-visual descriptors.

Automatic extraction of hydrographic features from SPOT satellite images

Summary: Carried out in behalf of Natural Resources Canada, these mandates have led to the development of a standalone program allowing for semi-automatic updating of contour maps of Canadian hydrographic zones (lakes and rivers) from images taken from the SPOT satellite. A Web version working within the context of a server is currently under development.

Result: CRIM contributed to the development of closed-captioning tools for real-time or pre-recorded broadcasts, for the benefit of deaf or hearing-impaired users of Canadian cultural content, and tools for the computer-assisted description of visual content for blind and visually impaired individuals.

ERIC7, an image searching environment for compatible MPEG-7 content

Summary: A system that automatically produces MPEG-7 descriptions was developed in the course of this project. This allows for indexing image banks according to their visual characteristics of color, form, texture, etc. 

Result: Functionalities were developed for searching, analyzing, exploring and classifying images.

Formal validation of role-based access control systems

The team has developed an approach for the formal validation of Role-Based Access Control (RBAC) systems for known workflows on which they operate. The approach relies on model checking technology and is implemented in a prototype tool.

Keyword detection in trader conversations on the energy transaction exchange floor [2007-09]

Summary: This project aimed at developing a speech analysis system that processes recordings of conversations involving traders negotiating on the energy transaction exchange floor.

Partners: The project was done in partnership with Univoc and Hydro-Québec Production and benefited from financial support from the PRECARN-Alliance program.

Result: The developed technology has been commercialized by Univoc as a product or service for audio mining in the areas of investigation and conformity verification, and management of transaction quality.

Lesion segmentation in fluorescent images

Summary: For this contractual mandate, we were called upon to develop a software application that performs automatic or semi-automatic segmentation of lesions appearing in a sequence of fluorescent images, and to estimate their sizes.

Proof-of-concept of an event-correlating module for embedded systems

A proof-of-concept of an event-correlating module for embedded systems has been developed, allowing for the automated analysis of the SNMP (Simple Network Management Protocol) traces produced in embedded hardware and for the correlation with abnormal network events, such as spurious or lost packets, occurring in certain network nodes.

Proof-of-concept of a test adaptation tool

Summary: Applications always during their lifecycle, and the testing procedures are particularly affected by the implemented changes. 

Result: Change propagation in this context becomes very expensive. To reduce this cost, we have developed a proof-of-concept of a test adaptation tool that uses a formal model of the application and a test suite. Given an updated version of the application and corresponding updated formal model, the tool allows the tester to identify tests that are still valid for the new version and those that need to be changed. For the tests that are now deemed invalid, the tool detects the first fragment inconsistent with the new version. This allows the developer to speed up the process of change propagation.

Property library for automated analysis of execution traces [2005-06]

The team has implemented a library of property patterns to automate analysis of execution traces produced in various systems, such as the GMS and UMTS telecommunication networks and train traffic control systems. The library includes around 80 patterns that are widely used in the area and facilitates the user's task in formalizing properties for model checking. 
Partner: Siemens AG

Prototype tool for the detection of bugs in multithreaded Java programs

We have developed a prototype tool for detecting bugs in multithreaded Java applications. Dozens of anti-patterns have been identified and documented, and detection modules for some of them have been implemented in the prototype. The tool has been extended with a dynamic analysis approach based on the development of observers (implemented in the form of automata) and a model checking analysis of log files that record the application’s activities. In line with this work, the team has also developed a Java code migration tool (from version 1.4 of the Java Virtual Machine to version 1.5).
