ENCODING MOTION VECTORS USING COMPETITION BETWEEN PREDICTORS

摘要

The invention relates to a method 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. According to the invention, the method includes: a step of determining (10) an optimal-selection subset containing some of said candidate vectors; a step of selecting (21) said motion vector from among the vectors of said optimal-selection subset; and a step of inserting (22) into said signal a piece of information designating the motion vector (p) selected from among the vectors of the optimal-selection subset.
