1. A method of processing imagery in an optical sorting system, said method comprising:
capturing imagery of a waste stream of moving items that includes a first item and a second item, the first item being deformed from its original configuration by crumpling so that captured imagery of the first item depicts a first surface region and a second surface region without depicting an intervening surface region found in an original configuration of the first item;
processing the captured imagery to identify 10 or more excerpts of image data;
analyzing said excerpts to identify a first group of excerpts that are phase coherent with each other, said analyzing identifying at least one excerpt that is not phase coherent with said first group of excerpts; and
processing image information from said first group of phase coherent excerpts to obtain a first item identifier for the first item, by decoding an encoded indicia formed on said deformed first item.
