Try to fiddle with the parameters to Classical IDF...
:-)

I too have seen that images that I (as a human) sees as pretty much  
identical will not appear to be similar to the GIFT. But I'm quite  
satisfied with the results anyway.

My results got better and better as I added more images. Using just a  
few hundred images, the results were crap. Adding a few thousand made  
it promising. Adding almost a hundred thousand images made the results  
pretty decent, for my purposes.
Color does seem to be an important part of the features though...
