Tomoaki Teshima	2a781bb616	remove raw SSE2/NEON implementation from mathfuncs.cpp * replace the implementation by universal intrinsic * make sure no degradation happens on ARM platform	7 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

Vadim Pisarevsky	85149f8686	hack solvePoly to finds roots of polynoms with zero higher-order coefficients. The roots are populated in this case, which is not valid, strictly speaking, but good enough for function like correctMatches. This solves http://code.opencv.org/issues/4330	10 years ago

Pavel Vlasov	45958eaabc	Implementation detector and selector for IPP and OpenCL; IPP can be switched on and off on runtime; Optional implementation collector was added (switched off by default in CMake). Gathers data of implementation used in functions and report this info through performance TS; TS modifications for implementations control;	11 years ago
Ilya Lavrenov	00f16e9178	neon	11 years ago
Adil Ibragimov	8a4a1bb018	Several type of formal refactoring: 1. someMatrix.data -> someMatrix.prt() 2. someMatrix.data + someMatrix.step * lineIndex -> someMatrix.ptr( lineIndex ) 3. (SomeType*) someMatrix.data -> someMatrix.ptr<SomeType>() 4. someMatrix.data -> !someMatrix.empty() ( or !someMatrix.data -> someMatrix.empty() ) in logical expressions	11 years ago
