Claim 8:
9. The method of claim 8 wherein, the pixel value differences are first pixel value differences and wherein, for each of the plurality of image regions:
determining the first image difference comprises determining from the first pixel value differences, a first maximum pixel value difference; and
determining whether the first set of image properties meets the first image property criteria comprises comparing the first maximum pixel value difference with a first maximum pixel difference threshold; and
wherein, for each of the plurality of image regions, determining the second set of image properties comprises determining based on at least the second and third representations, a second image difference representing a difference between the second and third representations of the image region and wherein, for each of the plurality of image regions, determining the second image difference comprises:
upscaling the third representation of the image region to generate a second upscaled representation of the image region, the second upscaled representation of the image region having the same pixel dimensions as the second representation of the image region;
for each pixel position in the second representation and the second upscaled representation, determining a second pixel value difference between respective pixels of the second representation and the second upscaled representation; and
determining from the second pixel value differences, a second maximum pixel value difference; and

wherein determining whether the second set of image properties meets the second image property criteria comprises comparing the second maximum pixel value difference with a second maximum pixel difference threshold, wherein the second maximum pixel difference threshold has a lower magnitude than the first maximum pixel difference threshold.
