I just finished writing about distance hashing functions with a slightly different angle. I visualized the distances between a bunch of images using two different techniques, one of which was pHash (discussed in the parent article). Mine isn't quite as in-depth performance wise, but it makes for pretty pictures. Some of my work is here: http://www.josephcatrambone.com/?p=619

I'm going to upload the SHA distance tonight.
