Heinz Hofbauer	a26c4fa2a2	Bugfix for an overlapping size of image and template for matchTemplate. Example: img of size 10x10 and templ of size 11x9. In subsequent code this will results in either width or height of corrSize to be zero (0). Line 261 will call crossCorr which will then have a zero size of either blocksize.width or blocksize.height resulting in a division by zero crach in lines 137 or 138.	12 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

Roman Donchenko	2dc8642508	Changed convexHull's documentation to essentially invert the meaning of ``clockwise``. The orientation of convexHull's result is currently the opposite of what the documentation would suggest: >>> import cv2, numpy as np >>> points = np.array([[0,0],[0,1],[1,0]], dtype=np.int32) >>> cv2.convexHull(points, clockwise=False) array([[[1, 0]], [[0, 1]], [[0, 0]]], dtype=int32) >>> cv2.convexHull(points, clockwise=True) array([[[0, 0]], [[0, 1]], [[1, 0]]], dtype=int32) Changing the function itself is probably not a good idea at this point, so this fixes the documentation by flipping the coordinate system. I also removed the mention of the origin, since it's irrelevant for this function.	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.
