elenagvo	b0e9d76ced	HAL for canny	7 years ago
Alexander Alekhin	baff521b63	imgproc(Canny): eliminate unnecessary operations drop manual loop unrolling: - don't block compiler optimizations - no effect on i5	7 years ago
Pavel Vlasov	a57718e1ac	ICV2017u3 package update; - Optimizations set change. Now IPP integrations will provide code for SSE42, AVX2 and AVX512 (SKX) CPUs only. For HW below SSE42 IPP code is disabled. - Performance regressions fixes for IPP code paths; - cv::boxFilter integration improvement; - cv::filter2D integration improvement;	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.

Pavel Vlasov	349d5ba012	--perf_instrument parameter now has int type and 0, 1, 2 modes (1 - simple trees, 2 - expanded trees for functions with same name but different calling address); Maximum depth limit var was added to the instrumentation structure; Trace names output console output fix: improper tree formatting could happen; Output in case of error was added; Custom regions improvements; Improved timing and weight calculation for parallel regions; New TC (threads counter) value to indicate how many different threads accessed particular node; parallel_for, warnings fixes and ReturnAddress code from Alexander Alekhin;	8 years ago

themightyoarfish	68d97502fe	Error message for wrong kernel size was insufficient. When setting a wrong kernel size, the error message only tells the user that it must be odd, however the conditions for rejection include values > 7 which must be communicated. Without that, the message would be incorrect and confusing if the user is unaware that only values 3, 5, 7 are accepted.	9 years ago

Pavel Vlasov	62854dcc0d	Enables support of IPP 9.0.0; HAVE_IPP_ICV_ONLY will be undefined if OpenCV was linked against ICV packet from IPP9 or greater. ICV9+ packets will be aligned with IPP in OpenCV APIs This will ease code management between IPP and ICV	10 years ago
Pavel Vlasov	14b006e808	IPP_VERSION_X100 was changed to: IPP_VERSION_MAJOR * 100 + IPP_VERSION_MINOR*10 + IPP_VERSION_UPDATE to manage changes between updates more easily. IPP_DISABLE_BLOCK was added to ease tracking of disabled IPP functions;	10 years ago
