Alexander Alekhin	3082ea82f9	core(merge): fix SIMD loop head processing	7 years ago
amatyuko	3ea2586a5a	Fix for SSE2 intrinsics problem in the part of saturation arithmetic processing during 32s->16u packed conversion - for some big negative values less than -INT_MAX+32767 the sign of the numbers is lost due to overflow that leads to incorrect saturation to MAX value, instead of zero. The issue is not reproduced with CV_ENABLED_INTRINSICS=OFF	7 years ago
luz.paz	2003eb1b9b	Misc. typos Found via `codespell -q 3 -I ../opencv-whitelist.txt --skip="./3rdparty"`	7 years ago
Alexander Alekhin	e90e398e7a	core(ocl): do not split refcount operations / compare - check result from CV_XADD() directly - decrease urefcount after unmap() call only	7 years ago
miaow1988	2988260107	Fixed the int size overflow bug of cv::Mat.push_back(). Changed the type of variable r from int to size_t. This change makes sure that a valid result of std::max(r + delta, (r*3+1)/2) can be passed into the reserve function.	7 years ago
Alexander Alekhin	89528d7c3a	core(ocl): don't expose exceptions from OpenCL callback to avoid silent crashes of OpenCL worker threads.	7 years ago

Vadim Pisarevsky	43820d89b4	further improvements in split & merge; started using non-temporary store instructions (#12063 ) * 1. changed static const __m128/256 to const __m128/256 to avoid wierd instructions and calls inserted by compiler. 2. added universal intrinsics that wrap MOVNTPS and other such (non-temporary or "no cache" store) instructions. v_store_interleave() and v_store() got respective flags/overloaded variants 3. rewrote split & merge to use the "no cache" store instructions. It resulted in dramatic performance improvement when processing big arrays * hopefully, fixed some test failures where 4-channel v_store_interleave() is used * added missing implementation of the new universal intrinsics (v_store_aligned_nocache() etc.) * fixed silly typo in the new intrinsics in intrin_vsx.hpp * still trying to fix VSX compiler errors * still trying to fix VSX compiler errors * still trying to fix VSX compiler errors * still trying to fix VSX compiler errors	7 years ago
Vadim Pisarevsky	9c7040802c	converted split() & merge() to wide univ intrinsics (#12044 ) * fixed/updated v_load_deinterleave and v_store_interleave intrinsics; modified split() and merge() functions to use those intrinsics * fixed a few compile errors and bug in v_load_deinterleave(ptr, v_uint32x4& a, v_uint32x4& b) * fixed few more compile errors	7 years ago
