Abstract
A method of analyzing an array of pixel-to-pixel dissimilarity values to identify a pixel which has a low pixel-to-pixel dissimilarity value and which has neighboring pixels which have a low pixel-to-pixel dissimilarity value; the method comprising filtering the pixel-to-pixel dissimilarity values and varying the spatial extent of the filter aperture in dependence upon a picture spatial activity measure.
