Vitaly Tuzov	9befb7a1d7	Merge pull request #14916 from terfendail:wsignmask_deprecated * Avoid using v_signmask universal intrinsic and mark it as deprecated * Renamed v_find_negative to v_scan_forward	6 years ago
Alexander Alekhin	1e9ad5476d	core(intrin): drop hasSIMD128 checks - use compile-time checks instead (`#if CV_SIMD128`) - runtime checks are useless	6 years ago
Alexander Alekhin	8c8715c4dd	fix static analysis issues	6 years ago
Michał Janiszewski	c8e6ce304f	Catch exceptions by const-reference Exceptions caught by value incur needless cost in C++, most of them can be caught by const-reference, especially as nearly none are actually used. This could allow compiler generate a slightly more efficient code.	6 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	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	9 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;	9 years ago
