I have a set of images (e.g. cars) and trying to perform feature detection using SIFT (actually, SIFT modification - A-SIFT, which is more robust to affine transformations) and I'm getting an extremely low results in matching even on the same models, same color and closely same view point.I'm barely sure, that the problem is car's surface is glossy (that's leads to huge variation of reflections on surface) and shadows & lighting (that's depends on location where photo was taken). Is there's image processing algorithms that can help me clean up images and/or decrease influence of that factors?I had a quick look at CiteSeerX and Google Scholar but found nothing.
