Claim One:
1. A method, comprising: estimating a global motion vector representative of motion of a digital first image with respect to a digital second image, the first and the second images forming part of a sequence of images and being made up of, respectively, a first and a second pixel matrix, said estimating the global motion vector including: estimating at least one motion vector of at least one region of the first image representative of motion of the at least one region from the first image to the second image, the estimating the at least one motion vector including: subdividing the at least one region of the first image into a plurality of pixel blocks; assigning to each block of the plurality a respective weighting coefficient calculated based at least in part on a respective inhomogeneity measure, the inhomogeneity measure of each block being a measure of non-uniformity of pixels of the block with respect to other pixels of the block; and estimating the at least one motion vector of said at least one region based at least in part on the weighting coefficient assigned to each block of the at least one region.
