Re: some questions

Hi,

using GIFT in a commercial project should be fine. If you modify it 
these modifications should be made available under GNU license as well. 
These are basically the constraints of the GNU license.

The quality of GIFT depends very much on the images. GIFT uses global 
features and features in fixed regions, this means that if you compare 
tissue it should be fine, whereas for objects it might not work this 
well. You would need to check the performance for your types of images, 
I think.

There are PHP interfaces, so the integration should be very easy.

GIFT scales all images to 256x256 before it extracts features, so image 
size is not important. For up to 150'000 images there should also be no 
speed or size problem.

Cheers, Henning
