Abstract :
We consider a new way to encode video sequences. The proposed method is based on second generation wavelets (SOW), a novel mathematic transform, successfully applied in 3D coding. This video coder is created by combining the wavelet theory and mesh geometry. With this and the SOW, we will be able to apply onto the video image, the mathematical transform to locate and to encode the error, results of the motion compensation process. This powerful signal processing theory allows a very well adapted coding of high frequencies. The main advantage is that these wavelets can be designed to fit exactly on singularities, shapes, textures, and edges. Hence, we can reduce redundancy and improve considerably coding efficiency over those peculiar settings. This new coder can be applied on all classical applications, such as very low bit rate transmissions, video streaming, vision conference and video on demand.
