As you asked for suggestions, here are some:
- Please let me choose which attributes to display, just like for the browser, so I have access to what information is important for my task (eg EXIF)
- rotated pics (eg 3°) are recognized as very different (eg 75)
- drop shadows - with elsewise same content etc. - provoke huge difference (in my example 14 points!)
- comparision of 2 files with big pictures (=see the details) and thumbails of their direct neighbours (very helpful for picture series).
- provides hint, what pic the program thinks is of better quality (so which one to keep). Works usually quite good as it is "intelligent", so for binary identical files the shorter filename is worse, the newer file is worse (as the older one has usually the original date), for different files the smaller ones but depending on compression ratio,...
- Highlight what is different between two similar images (size, color depth, compression ratio,...).
- offer (semi-)automated tasks like move, replace, rename,... based on results
- let me choose the comaprision methods used (histogram, SVMs,...) and their sensibilities
