Abstract
An efficient method for determining the compressed rate of a digital image with a given set of compression parameters, the method comprises the steps of forming a plurality of non-overlapping image regions, each of which includes a plurality of contiguous pixels, from the digital image where the total number of pixels contained in all of the contiguous regions is less than the total pixels in the digital image; compressing each region with the given set of compression parameters; and, combining the resulting rate from each region to form an estimate of the compressed rate of the digital image.
