ABSTRACT:
A system relates to a process for correcting the estimation of movement in frames including periodic structures in a system for determining movement vectors by comparison of blocks of frames, an error matrix being associated with each block. The process is characterized in that it includes the stages of determining adjacent periodic blocks and of selecting a single movement vector for all of these blocks. The process applies, in particular, in the sphere of television.
