I want to use the sobel filter for the image matching ,but i don't know how to make the sobel descriptor in the opencv? For example ,if I want to use the 5*5 sobel block as the matching descripotr,what should i do?

well,if you want feature based ,as i know,it is the same. you can use sobel(src,dst1,1,0,5);sobel(src,dst2,0,1,5); you can reference here in detial http://courses.cs.washington.edu/courses/cse576/05sp/projects/proj1/artifacts/cavender/Project1.htm
