Rotation invariant multiple template occurrence in image Opencv

I have various template images and one big image with multiple ocurrence of each template in it, but are rotated.

I have tried with SIFT and SURF but only work with one ocurrence of each template and matchTemplate is not rotation invariant. I am programming in C++.

Please, could you give me any suggestions? Thanks.

Solution

  • You can use log-polar template matching.

    You can find more explanation here: http://www-cs.engr.ccny.cuny.edu/~wolberg/pub/icip00.pdf

    In this paper described method for finding maximum correlated template. But with small modifications it can be used to find multiple occurrences of template.
