    摘要： A method for decoding a stream of coded data to reconstruct a current block of a sequence of images is disclosed. The method comprises the steps of: reconstructing for the current block a first item of motion data from a stream of coded data, identifying a first prediction block with the first item of motion data, determining a second item of motion data by template matching, identifying a second prediction block with the second item of motion data, reconstructing the current block from the first and second prediction blocks. The step of determination of the second item of motion data is a function of the first distortion calculated between the first prediction block and the second prediction block.

    摘要： The process for coding the current block comprises a step of selecting the predicted block from among candidate blocks, the selection being dependent on a difference DBdrx,dry between the co-located block of the current image block lying in an image of type B and the block of a reference image, the latter block being designated by the motion vector with components drx, dry which is allocated to co-located block and which is colinear with the motion vector Vp allocated to the current block and designating the candidate block. The process relates to data compression, the transmission of digital images using the video coding standard comprising a direct prediction mode, for example the h263, MPEG4 or h261 standard.
