I was just trying to compare two images by feature point matching using SIFT. I am using SURF type Descriptor Extractor to do this. Now for some GIF images the descriptor extractor returns empty. Why & What to to in this case?

oh, quite simple in this case : opencv can't load gif images.

you'll have to convert them to, e.g. png using some external program before.
