Abstract
A method is provided for coding a current image that has previously been partitioned into blocks. The method includes, for a current block that is to be coded: partitioning the current block at least once into a plurality of subblocks; and representing) the partitioning of current block in the form of a first digital information sequence. The coding method further includes predicting the partitioning of the current block relative to the partitioning of a block that has already been coded and then decoded and that is represented in the form of a second digital information sequence, by comparing the first and second sequences with each other or by comparing the corresponding partitionings with each other, and then by determining residual digital information representative of the comparison in application of a predetermined comparison criterion; and encoding the residual digital information as determined.
