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
Pavel Vlasov	35c7216846	IPP for OpenCV 2017u2 initial enabling patch;	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
