Vadim Pisarevsky	6473018d69	eliminated trailing whitespaces	8 years ago
mschoeneck	4a4d94f266	Merge pull request #8694 from mschoeneck:Canny Parallelize Canny with custom gradient (#8694) * New Canny implementation. Restructuring code in parallelCanny class. Align mag buffer and map. * Fix warnings. * Missing SIMD check added. * Replaced local trailingZeros in contours.cpp. Use alignSize in canny.cpp * Fix warnings in alignSize and allocate just minimum extra columns. * Fix another warning in map.create. * Exchange for loop by do loop to avoid double check at the beginning. Define extra SIMD CANNY_CHECK to avoid unnecessary continue.	8 years ago

Pavel Vlasov	11c2ffaf1c	Update for IPP for OpenCV 2017u2 integration; Updated integrations for: cv::split cv::merge cv::insertChannel cv::extractChannel cv::Mat::convertTo - now with scaled conversions support cv::LUT - disabled due to performance issues Mat::copyTo Mat::setTo cv::flip cv::copyMakeBorder - currently disabled cv::polarToCart cv::pow - ipp pow function was removed due to performance issues cv::hal::magnitude32f/64f - disabled for <= SSE42, poor performance cv::countNonZero cv::minMaxIdx cv::norm cv::canny - new integration. Disabled for threaded; cv::cornerHarris cv::boxFilter cv::bilateralFilter cv::integral	8 years ago

Artem Lukoyanov	c4ae5c0ee5	Added assertios to remap and warpAffine functions Remap and warpAffine functions do not support more than 4 channels in Bicubic and Lanczos4 interpolation modes. Assertions were added. resolve #8272	8 years ago
vartenkov	3fbe1f8d64	Fix multichannel warping with BORDER_CONSTANT Warping a matrix with more than 4 channels using BORDER_CONSTANT and INTER_NEAREST, INTER_CUBIC or INTER_LANCZOS4 interpolation led to undefined behaviour. This commit changes the behavior of these methods to be similar to that of INTER_LINEAR. Changed the scope of some of the variables to more local. Modified some tests to be able to detect the error described.	8 years ago

Alexander Alekhin	ba8a6e3533	ocl: don't use vload4 for 3 channel images	8 years ago
chacha21	27cfe31b64	more ICV_HLINE specific cases added ICV_HLINE custom implementations for element sizes up to 32 but timings show that it is not very relevant for sizes >= 12	8 years ago
chacha21	92a3dbe18f	more ICV_HLINE optimization added 64b optimization for 3 channels case not added 64b optimization for 4 channels case since timings did not show any improvement split ICV_HLINE cases into inline functions instead of macro for code size reduction, without significand speed drawback at first sight	8 years ago
Fangjun KUANG	34c70e7a1c	Fix typos.	8 years ago
Jejos	5169c79978	fix medianBlur accessviolation medianBlur called with "empty" source and ksize >= 7 crashes application with accessviolation. With this extra assert this is avoided and the application may normally catch the thrown exception.	8 years ago

Alexander Alekhin	4c7aa8645a	ocl: validate arguments in KernelArgs constructor - don't use undefined flag=0. It should be CONSTANT instead. - don't allow 'UMat* m=NULL' argument (except LOCAL/CONSTANT flags). This case is not handled well to provide NULL __global pointers. It is better to use '-D' macro defines instead (at least for performance)	8 years ago
