kocheganovvm	086db9d6db	Introduce CV_COMP_CHISQR_ALT, an alternative method to calculate ChiSquare Histogram comparison There's some disagreement about the correct formula. has its supporters, however, for texture analysis, the newly introduced formula became standard. The commit enables both uses without breaking backward compatibility. First contributor of this commit was sperrholz.	11 years ago

Roman Donchenko	f90fd5b0da	Split CLAHE into its own file, because it's faster that way. Yes, it's as ludicrous as it sounds, but it's still true. Bizarrely, the previous commit makes CLAHE run about 10% slower on Android, even though it doesn't even touch any CLAHE code. Splitting it off fixes that, although the reason it does is a mystery for the ages. It's cleaner when it's in its own file, anyway. ;=]	12 years ago
Roman Donchenko	29b13ec1de	Replaced most of the usages of parallel_for with that of parallel_for_. This should allow many algorithms to take advantage of more parallelization technologies.	12 years ago
ericgreveson	e7995b4d5d	Take account of multi-channel matrices when comparing histograms Ensure that all channels are considered when comparing multi-channel histograms	12 years ago
ericgreveson	19794e6857	Fix for spurious assert in cv::compareHist When comparing histograms that look like multi-channel images (e.g a 3D histogram, of 4x4x4 bins, might appear as a CV_32FC4 matrix), cv::compareHist would complain because it was expecting the matrix type() == CV_32F. Now we test matrix depth() == CV_32F instead.	12 years ago

Daniil-Osokin	7d94236c14	TBB version of calcHist	12 years ago
Andrey Kamaev	0bbba847a4	Fix equalization formula in equalizeHist function & rewrite in C++ Old implementation did lut[i] = 255 * (count(Y <= i)) / (width * height) which actually shifts uniform histograms. From now histogram is equalized as C = count(Y == min(Y)) lut[i] = 255 * (count(Y <= i) - C) / (width * height - C)	12 years ago
