Yan Wang	6e7050555e	Optimize pyrUp_unrolled() by mad function. It could improve performance when image size is large. E.g. OCL_PyrUpFixture_PyrUp.PyrUp/18	10 years ago
orestis	a7757b0eb6	Fix anchor for small symmetrical column filters. In the unoptimized version of small symmetrical column filters, when we try to detect if the kernel, ky, is equal to [1;2;1] or [1;-2;1] we should take into consideration that the anchor points in the middle element.	10 years ago
Yan Wang	184b6e314c	Fix canny segment fault (Bug #3978 ) Avoid stack overflow based on std::vector cause std::vector::resize() segmentation fault.	10 years ago

Miroslav Benes	5b1fd739d9	Add Triangle thresholding algorithm Add Triangle method for automatic threshold computation next to the existing Otsu's method. Triangle deals better with images whose histogram does not contain dominant peak. See paper Zack GW, Rogers WE, Latt SA.: Automatic measurement of sister chromatid exchange frequency.
