Stefano Allegretti	91817bffe1	Merge pull request #21275 from stal12:CCL_improvements Improve CCL with new algorithms and tests * Improve CCL with new algorithms and tests * Split CCL test into dedicated tests cases	3 years ago
eplankin	175bcb1734	Merge pull request #21258 from eplankin:fix_threshold_to_zero_ipp_bug Fixed threshold(THRESH_TOZERO) at imgproc(IPP) * Fixed #16085: imgproc(IPP): wrong result from threshold(THRESH_TOZERO) * 1. Added test cases with float where all bits of mantissa equal 1, min and max float as inputs 2. Used nextafterf instead of cast to hex * Used float value in test instead of hex and casts * Changed input value in test	3 years ago
Vincent Rabaud	3da17c42a4	Use NaN-safe clip function. This is to prevent more NaN to int conversions like in #21111.	3 years ago
Alexander Alekhin	72c55b56f2	imgproc: catch NaNs in clip(), use table index debug check - no NaN propagation guarantee	3 years ago
Vincent Rabaud	542b3e8a64	Fix harmless signed integer overflow. When computing: t1 = (bayer[1] + bayer[bayer_step] + bayer[bayer_step+2] + bayer[bayer_step2+1])G2Y; there is a T (unsigned short or char) multiplied by an int which can overflow. Then again, it is stored to t1 which is unsigned so the overflow disappears. Keeping all unsigned is safer.	3 years ago
Alexander Alekhin	659cf7249e	imgproc(ocl): fix resizeLN, avoid integer overflow	3 years ago
Alexander Alekhin	0c0b1ec9ae	imgproc(test): add bit-exact tests for YUV cvtColor conversions	3 years ago
Vincent Rabaud	1a1a7bbbfd	Merge pull request #21112 from vrabaud:3.4_luv_overflow * Fix integer overflow in cv::Luv2RGBinteger::process. For LL=49, uu=205, vv=23, we end up with x=7373056 and y=458 which overflows yx. imgproc(test): adjust test parameters to cover SIMD code	3 years ago
yuki takehara	a6277370ca	Merge pull request #21107 from take1014:remove_assert_21038 resolves #21038 * remove C assert * revert C header * fix several points in review * fix test_ds.cpp	3 years ago
Vincent Rabaud	d4741eece1	Fix H clamping for very small negative values. In case of very small negative h (e.g. -1e-40), with the current implementation, you will go through the first condition and end up with h = 6.f, and will miss the second condition.	3 years ago

Tiago De Gaspari	3cf4375387	Merge pull request #19842 from gasparitiago:3.4 Update rotatedRectangleIntersection function to calculate near to origin * Change type used in points function from RotatedRect In the function that sets the points of a RotatedRect, the types should be double in order to keep the precision when dealing with RotatedRects that are defined far from the origin. This commit solves the problem in some assertions from rotatedRectangleIntersection when dealing with rectangles far from origin. * added proper type casts * Update rotatedRectangleIntersection function to calculate near to origin This commit changes the rotatedRectangleIntersection function in order to calculate the intersection of two rectangles considering that they are shifted near the coordinates origin (0, 0). This commit solves the problem in some assertions from rotatedRectangleIntersection when dealing with rectangles far from origin. * Revert type changes in types.cpp and adequate code to c++98 * Revert unnecessary casts on types.cpp Co-authored-by: Vadim Pisarevsky <vadim.pisarevsky@gmail.com>	4 years ago

Aaron Greig	f3f46096d6	Relax accuracy requirements in the OpenCL sqrt perf arithmetic test. Also bring perf_imgproc CornerMinEigenVal accuracy requirements in line with the test_imgproc accuracy requirements on that test and fix indentation on the latter. Partially addresses issue #9821	4 years ago
