2012-11-23 01:22:34 -0600 | asked a question | Good feature descriptor/matcher for matching photo of different size Hi All, First of all, sorry if answer to this question is too obvious/easy. I have been playing around opencv for couple weeks, but without any background in computer vision, i am hitting a road block now and am hoping your expertise can point me to the right direction :) i am trying to match two identical images but with different size (dimension), or one might be a cropped version of the other. There is no rotation variation. Here are the steps that my program follows
I have tried using SURF for step 1 and 2 and a brute force L2 matcher for step3. It works quite well, but since it is patented, I am trying to find a alternative. I have tried a few different combination of feature detector and descriptor extractor, but the result is not good. Is there a good combination of "feature detector/descriptor extractor/matcher"choice that might worth a try? Thanks so much |
