Hi, I have a problem with detecting logos on page. So far I've tried to get screenshot of webpage and work with it but i found downloading all images separately and working with them one by one to be better solution. Since my logo templates are mostly not rotated but may be different sizes I've decided to use SIFT. Currently I'm getting a lot of mismatches. I've been thinking about binarizing image since in logos the shape is the most important
