Abstract
A method for decomposing each field of movement of an image according to a coding tree and for identifying by a menu each movement vector present in the image by accompanying each vector by its codeword.
Claims6
A method of coding with adjustable parameters of a field of movement in a sequence of animated images comprising the steps of:
- dividing an image into a plurality of macroblocks of given dimensions;
- calculating a coding tree for each of said macroblocks in order to obtain a plurality of vector menus corresponding to said image;
- decomposing each field of movement of said image according to said coding tree;
- and
- identifying, using said menus, each movement vector present in said image by accompanying each vector by its address in said menus.
