摘要：
The invention relates to a method of encoding a source image sequence. The inventive method comprises: motion/texture decomposition, such as to produce, for at least some of the source images, information that is representative of motion, known as motion images, and information that is representative texture, known as texture images; and wavelet encoding, said encoding being applied to difference images (residue) which are obtained by comparing a motion image, or texture image respectively, with a corresponding estimated image.
