Abstract
A motion estimator operating on a recursive mode reduces the number of operations per pixels required by the particular coding process being implemented. The coding process includes the MPEG standard. A method is based on the correlation existing among motion vectors associated to macroblocks in a common position in temporally adjacent images. The method is also associated to macroblocks belonging to the same picture and spatially adjacent to the current macroblock being processed. By using this double correlation, the calculation burden is reduced.
