Hi,

I'm comparing the outputs of the self similarity code in OpenCV with the outputs of this Matlab Package: http://www.robots.ox.ac.uk/~vgg/software/MKL/

The outputs are different. Can someone please tell me on which Matlab package the OpenCV implementation is based upon and why there might be differences?

Thanks,

Gil.

Guess you need to ask the author, see https://github.com/Itseez/opencv/blob/ef91d7e8830c36785f0b6fdbf2045da48413dd76/modules/contrib/src/selfsimilarity.cpp#L45 . (Btw: is it that bad that it is different? Guess, if you'd implement it just knowing the paper, your output would be also different).

Thanks, I mailed him.

K, let us know what comes out, if he responses.

He responded, he said that the code in OpenCV was written long before the Matlab package I used and, so I can't expect getting the same results.
