Visits of international scientists

Visit to Delft University of Technology

Participant : Guillaume Gravier.

Guillaume Gravier was invited to the Multimedia Information Retrieval Lab at Delft University of Technology for one week in May 2011. He gave a seminar entitled Speech, Language and Multimedia at IRISA/INRIA Rennes and participated in the organization of MediaEval 2011, an international benchmark initiative in multimedia processing. A EU project involving TU Delft and IRISA/INRIA Rennes, initiated during his visit in Delft, has been submitted to the FET Open program.

Visit to the BUSIM speech processing group at Bogazici University

Participant : Julien Fayolle.

Julien Fayolle spent three months, from May to July 2011, in the BUSIM speech processing group at Bogazici University (Istanbul, Turkey) to work on lexical-phonetic automata for spoken utterance retrieval in collaboration with Murat Saraçlar. Whereas the state-of-the-art approaches consist in a late fusion of the results of phonetic and lexical searches, the idea was to adapt the Murat Saraclar's spoken utterance retrieval methods to a new representation combining both lexical and phonetic levels earlier than the retrieval step.

Doctoral Internship from Florida State University

Participants : Guillaume Gravier, Patrick Gros, Hervé Jégou.

Jiangbo Yuan spent five months in the TexMex project-team to work on audio indexing for video copy detection. He has contributed to the submission of INRIA at copy detection task, working on our audio indexing engine, more precisely on the post-verification step. He then worked on the detection of near-duplicate patterns in very large datasets of vectors.

His venue was funded by the EIT ICT Labs OpenSEM project.

Visit to the Czech Technical University in Prague

Participant : Hervé Jégou.

Hervé Jégou spent one week (October 2011) in the Center of Machine Perception at the Czech Technical University, Prague, to initiate a collaboration with Pr. Jiri Matas and Dr. Ondrej Chum. During this visit, he gave an invited talk at the 29th Pattern Recognition and Computer Vision Colloquium, entitled “Approximate search as a source coding problem, with application to large scale image retrieval”. This visit was the opportunity to start a joined work on image search.

Visit of members of the University of Reykjavík and Videntifier Technologies

Participant : Laurent Amsaleg.

Björn Þór Jónsson from the School of Computer Science, Reykjavik University, Iceland and with Herwig Lejsek, Videntifier Technologies, Iceland spent one week in the team. They came to participate to the large scale high dimensional indexing experiments involving more than 30 billion SIFT descriptors.
