I have a really simple problem compared to recognizing faces :) I try to
> detect the square areas around pictures in the preview on a flatbed image
Ah, I made a small, crude program named "Texas" a few weeks ago... it tries
to detect "objects" in images - you can tune it's parameters to detect
individual characters, words, lines, paragraphs, or images. It's made using
openCV and written in C++.
Texas also has an option to parse a comic book page and extract the
individual picture "boxes".
I had intended to use it for literally "compressing" text in scanned images
- that is, if there's too much whitespace left between lines or words, you
could move the lines/words a bit more "together" to save space in the
image... maybe I'll implement it one day :)
Not sure how useful it would be to you, you might want to give it a try :
Yep, as you and Michael noted 100*150 pixels is not enough for a group

I'll think about it...
