Alexander Alekhin	a56b221559	core: cv::Range() ostream write operator remove from DNN module headers	6 years ago
Alexander Alekhin	7453a6938a	core(test): extra tests/fixes for merge/split (#12171 ) * core(test): merge hang test * core(merge/split): fix intrin optimization	6 years ago
Alexander Alekhin	5c3880d302	core(intrin): avoid symbols duplication from SIMD128/256 cases All vx_call() must be wrapped into own simd128/simd256/simd512 namespace ``` namespace CV__SIMD_NAMESPACE { ... vx_call declaration is here ... } ```	6 years ago
Alexander Alekhin	9eaa583bfb	core: dump neighbour cache directories (from old OpenCV versions) - use '3.4.x' cache name for current maintenance series (there are no serious changes between releases) - message is shown only once during creation of new cache directory - use OPENCV_CACHE_SHOW_CLEANUP_MESSAGE=0 to hide this warning	6 years ago
Alexander Alekhin	3082ea82f9	core(merge): fix SIMD loop head processing	6 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	6 years ago
Alexander Alekhin	3f302cabb8	core(test): intrinsic tests for all dispatched CPU optimizations - tests for both SIMD128 / SIMD256 - different dispatched + baseline(SIMD128) intrinsics	6 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	6 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.	6 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	6 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	6 years ago
