| Marc Chaumont was born in November 1976, in France. He received his engineer diploma in computer sciences at the INSA (National Institute of Applied Sciences) of Rennes, France in 1999 and his Ph.D. in computer sciences at the INRIA of Rennes in 2003. His Ph.D. thesis was about video objects representations, with dynamic coding and scalability functionality, in the video compression area. He has carry on for one year its research activity at the INRIA and for one another year at the University Technological Institute of Bayonne, France as a Visiting Assistant Professor. During this last year, his research has focus on face tracking using a deformable 3D face model. Since September 2005, he is in the LIRMM (Laboratory of Computer Science, Robotic and Microelectronic) of Montpellier as an Assistant Professor. His current interests areas are video compression and watermarking and and to a lesser extent segmentation & tracking in videos. |
Research Topics :Watermarking:Watermarking is the art of modifying a media (picture, sound, vidéo...) in order to hide inside it, a message most of the time related with the media and most of the time in an inperceptible way. In this thematique, we are looking to watermarking scheme robust to the degredations occuring after the watermarking. Those degredations may be the classical treatments such that filtering, compression... We thus studying informed approaches (appeared in 1998). We are also working on the security issues (watermarking community is working on it since 2005) to ensure the communication secrecy. An attacker should not be able to extract a secrecy such a key or a message. Compression: Compression is the art of reducing the information redondancy of a message. Compression is a major concern of data storage and data tranmission. For videos, pictures or sounds, compression is often lossy. In this thematique, we are proposing improvements, or fonctionalities adds, to video compression standards such as H.264/AVC (MPEG-4 Part10) or SVC (Scalable Video Coding). The watermarking is one of the fonctionality we are looking to intergrate into videos codecs. Analysis, Image and Video Treatments (segmentation, tracking in vidéos, …): I have essentially work in this thematique until 2006. I still occasionally contribute in this theme. I have worked on segmentation and on videos objects tracking. I have also work on real-time face tracking with a deformable 3D model using active models. Key-words: Watermarking and Security, Compression, Segmentation, Video tracking. |
