RENATER2 Image / Video Transmission, Storage and Manipulation of 3D Images In image / video transmission, storage, and manipulation, the key issue is representation. One strives to find representations of images and video that are efficient (requiring a small amount of bits to transmit or store) yet easy to manipulate (e.g., easy to find what one is looking for in a database). The group carries out research in image and video compression using a variety of approaches ranging from wavelets and fractals, to ideas from pattern recognition and computer vision. Also under study are methodologies and techniques for image / video indexing and editing. Research in human visual perception is an essential part of this effort since, in many applications, the images after processing are viewed by humans, and the subjective quality of images is an important performance criterion. Applications of this research include video phone, teleconferencing, and multimedia databases. 3D interactive modeling, with real-time constraints, in a strongly reactive context constitutes the main collaboration axis between the two laboratories.
