Abstract
A method of encoding an input image divided into a set of image blocks and stored in computer readable memory. In one embodiment, the method comprises determining a sequence of block test patterns, each (i) identifying, for each image block of the set, a separate portion of the image block; and (ii) determined to minimize a maximum unidentified portion size of the input image when used on all image blocks of the set; assembling an active block test pattern comprising one of the block test patterns; comparing, based on the active block test pattern, at least one image block of the set with a reference image comprising a previously encoded copy of the input image to generate a block change detection; and encoding, based on the block change detection, a changed image block of the at least one image block to generate a portion of an encoded image.
