METHOD OF MOTION ESTIMATION FOR IMAGE SEQUENCES, IN PARTICULAR FOR VIDEO SIGNAL PROCESSING

A method is described for estimating the motion for image sequences carrying out a decimation of the function used for the extraction of the characteristic parameters of an image block. The method is iterated by decreasing the function decimation and carrying out the block-matching on a set of the best matchings of the preceding steps. The method does not require the recalculation of the parameters on the reference image for each block to be matched; moreover, in the extraction of the characteristic parameters of a block, the use of the Integral Projections is not mandatory but one of the possible variants only (FIG. 1).
