A method and apparatus are provided for encoding an image sequence. The method includes the following steps, for at least one group of blocks of an image: determining, for each block, at least one parameter characteristic of said block; forming at least one cluster including the blocks having at least one similar characteristic parameter; encoding the blocks of said cluster, the similar characteristic parameter(s) associated with said cluster being encoded only once; encoding the blocks that do not belong to any cluster, the characteristic parameter(s) associated with each of said blocks not being encoded; generating a data stream; and inserting into said stream, at least one piece of information on the partitioning of the group(s), in order to identify the outer block(s) within a group. |
