Method for coding a sequence of images implementing a prediction of at least one block of a current image (Ip) of said sequence on the basis of a block of a reference image (Iref) previously sliced into blocks, said prediction associating at least one block of a current image (Ip) of said sequence with at least one corresponding block in at least one intermediate image (Ia) temporally located between said reference image and said current image, to be forward motion compensated, said intermediate image or images having been previously coded, comprising the following steps: - determination of a first plurality of motion vectors, termed control vectors, associated with the current image, said control vectors each being representative of a displacement between a vertex of said given block of the reference image and a corresponding position of said vertex in the current image, - slicing, taking account of the motion between the reference image and the current image, of said given block into sub-blocks implementing at least one slicing iteration, until the attaining, when said slicing implements at least two iterations, of a first predetermined slicing stopping criterion, defining a first partition, - determination of a second plurality of motion vectors, termed control vectors, associated with the intermediate image, and each representative of a displacement between a vertex of said given block of the reference image and a corresponding position of said vertex in the intermediate image, - slicing, taking account of the motion between the reference image and the intermediate image, said given block into sub-blocks implementing at least one slicing iteration, until the attaining, when said slicing implements at least two iterations, of a second predetermined slicing stopping criterion, defining a second partition, the method is characterized in that said first and second slicing stopping criteria belong to the group comprising: - a minimum size of a sub-block; - a maximum number of slicings; - a difference of less than a predetermined threshold between the control vectors associated with two sub-blocks, and in that it comprises the obtaining of a common partitioning into sub-blocks for said given block, termed base sub-blocks, by union of said first and second partitions, and a prediction of said current image on the basis of said intermediate image, said prediction comprising the following steps: - determination of a first set of control vectors for said base sub-blocks, on the basis of the control vectors associated with the block of the current image; - determination of a second set of control vectors for said base sub-blocks, on the basis of the control vectors associated with the block of the intermediate image, - forward motion compensation of a base sub-block with the aid of said second set of control vectors delivering a sub-block of said intermediate image, - prediction of said current image by forward motion compensation of said sub-block of said intermediate image towards a corresponding sub-block of said current image with the aid of said first set of control vectors. - determination of a first plurality of motion vectors, termed control vectors, associated with the current image, said control vectors each being representative of a displacement between a vertex of said given block of the reference image and a corresponding position of said vertex in the current image, - slicing, taking account of the motion between the reference image and the current image, of said given block into sub-blocks implementing at least one slicing iteration, until the attaining, when said slicing implements at least two iterations, of a first predetermined slicing stopping criterion, defining a first partition, - determination of a second plurality of motion vectors, termed control vectors, associated with the intermediate image, and each representative of a displacement between a vertex of said given block of the reference image and a corresponding position of said vertex in the intermediate image, - slicing, taking account of the motion between the reference image and the intermediate image, said given block into sub-blocks implementing at least one slicing iteration, until the attaining, when said slicing implements at least two iterations, of a second predetermined slicing stopping criterion, defining a second partition, - a minimum size of a sub-block; - a maximum number of slicings; - a difference of less than a predetermined threshold between the control vectors associated with two sub-blocks, - determination of a first set of control vectors for said base sub-blocks, on the basis of the control vectors associated with the block of the current image; - determination of a second set of control vectors for said base sub-blocks, on the basis of the control vectors associated with the block of the intermediate image, - forward motion compensation of a base sub-block with the aid of said second set of control vectors delivering a sub-block of said intermediate image, - prediction of said current image by forward motion compensation of said sub-block of said intermediate image towards a corresponding sub-block of said current image with the aid of said first set of control vectors.
