i am implementing SIFT algorithm , where my purpose of using this is that i have a set of images and i want to find the best match against a single image which i have kept it as 'template image' , SIFT gives us matches and scores in return , where 'matches' represent the descriptors that were found to be same in both image, and 'scores' determined by euclidean method, now i am stuck at the point that how can i evaluate the best match amongst all the images with my template image, i figured out that when there is a exact match between two images the 'score' turns out to be zero , because descriptors position in both the images are same,so can anyone guide me through that how shall i go about it that i can say this image is the best match or the second best match against template but using 'scores'.
