Abstract:
A method is provided for encoding an image signal that includes motion information, by selecting a motion vector from among a set of at least three candidate vectors for at least one actual block of an actual image to be encoded. The method includes: determining an optimal-selection subset containing some of the candidate vectors; selecting the motion vector from among the vectors of the optimal-selection subset; and inserting into the signal a piece of information designating the motion vector selected from among the vectors of the optimal-selection subset.
