In the changelog of version 2.4.7 there is a mention of "New optimization for histograms" Can some one please explain where can I find the details of these "optimizations". The reason I ask is because, I am seeing discrepancies between the outputs of histogram equalization from version. 2.4.3 and 2.4.9.

I appreciate any help... Thanks

Ok thanks! I found some comments about the code change here: (http://code.opencv.org/projects/opencv/repository/revisions/0bbba847a413f86e91d81f28f9cc7bd04a3375c9)

Can you tell from this what changes are done to the code conceptually?

Thanks

just click the diff there ? (still puzzled, what what you mean with: 'conceptually' )
