Abstract
A method for predicting a current block belonging to a current image with a view to the coding or the reconstruction of the current block. The method includes determining for the current block a reference block from at least one motion data previously associated with the current block. The fulfillment of a predefined condition is is verified. The predefined condition being representative of a temporal variation between the image data of the reference block and the image data of a prediction block of the reference block previously determined from at least one motion data associated with the reference block. The motion data is modified according to the result of the verification, and a final prediction block for the current block is generated from the motion data of the current block.
