If you don't have pure background then you will end up with more and false keypoints. MK-RoD is prone to false SIFT keypoint matches. So simply, the algorithm will not work if you use background.
Hi Caglar, you have done a great work, I have a question. Why is it recommendable to use a pure black background? I mean, what happens with the algorithm and the keypoints if you don´t have that background?
this code is not working with other input image. when we take other input image, we get error massage like described by Bipul and after this, if we take right image from input database than it show error.
sorry for english.....
