Abstract
A method is provided for encoding an image sequence, including the step of dividing a reference image into blocks and a prediction step that includes the following steps: determining monitoring vectors associated with a common image and dividing the same into sub-blocks defining a first partition; determining monitoring vectors associated with an image to be compensated and dividing the same into sub-blocks defining a first partition obtaining a common partitioning into basic sub-blocks; determining first and second sets of monitoring vectors for the basic sub-blocks; movement-compensating a sub-block of the image to be compensated towards a sub-block of the common image.
