Sayed Adel	f2fe6f40c2	Merge pull request #15510 from seiko2plus:issue15506 * core: rework and optimize SIMD implementation of dotProd - add new universal intrinsics v_dotprod[int32], v_dotprod_expand[u&int8, u&int16, int32], v_cvt_f64(int64) - add a boolean param for all v_dotprod&_expand intrinsics that change the behavior of addition order between pairs in some platforms in order to reach the maximum optimization when the sum among all lanes is what only matters - fix clang build on ppc64le - support wide universal intrinsics for dotProd_32s - remove raw SIMD and activate universal intrinsics for dotProd_8 - implement SIMD optimization for dotProd_s16&u16 - extend performance test data types of dotprod - fix GCC VSX workaround of vec_mule and vec_mulo (in little-endian it must be swapped) - optimize v_mul_expand(int32) on VSX * core: remove boolean param from v_dotprod&_expand and implement v_dotprod_fast&v_dotprod_expand_fast this changes made depend on "terfendail" review	5 years ago
Paul E. Murphy	b2135be594	fast_math: add extra perf/unit tests Add a basic sanity test to verify the rounding functions work as expected. Likewise, extend the rounding performance test to cover the additional float -> int fast math functions.	5 years ago
Alexander Alekhin	f1f0f630c7	core: disable I/O perf test - can be enable separately if needed - not stable (due storage I/O processing)	6 years ago
Vitaly Tuzov	00c9ab8c23	Merge pull request #13317 from terfendail:norm_wintr * Added performance tests for hal::norm functions * Added sum of absolute differences intrinsic * norm implementation updated to use wide universal intrinsics * improve and fix v_reduce_sad on VSX	6 years ago
Hamdi Sahloul	a39e0daacf	Utilize CV_UNUSED macro	6 years ago
Vadim Pisarevsky	80b62a41c6	Merge pull request #12411 from vpisarev:wide_convert * rewrote Mat::convertTo() and convertScaleAbs() to wide universal intrinsics; added always-available and SIMD-optimized FP16<=>FP32 conversion * fixed compile warnings * fix some more compile errors * slightly relaxed accuracy threshold for int->float conversion (since we now do it using single-precision arithmetics, not double-precision) * fixed compile errors on iOS, Android and in the baseline C++ version (intrin_cpp.hpp) * trying to fix ARM-neon builds * trying to fix ARM-neon builds * trying to fix ARM-neon builds * trying to fix ARM-neon builds	6 years ago
Vadim Pisarevsky	54279523a3	Merge pull request #12437 from vpisarev:avx2_fixes * trying to fix the custom AVX2 builder test failures (false alarms) * fixed compile error with CPU_BASELINE=AVX2 on x86; raised tolerance thresholds in a couple of tests * fixed compile error with CPU_BASELINE=AVX2 on x86; raised tolerance thresholds in a couple of tests * fixed compile error with CPU_BASELINE=AVX2 on x86; raised tolerance thresholds in a couple of tests * seemingly disabled false alarm warning in surf.cpp; increased tolerance thresholds in the tests for SolvePnP and in DNN/ENet	6 years ago
Alexander Alekhin	b24fc6954d	core(perf): fix addScalar test keep the same type for passed Scalar values	6 years ago
Alexander Alekhin	b0ee5d9023	core: CV_NODISCARD macro with semantic of [[nodiscard]] attr [[nodiscard]] is defined in C++17. There is fallback alias for modern GCC / Clang compilers.	6 years ago
Alexander Alekhin	65726e4244	core(hal): improve v_select() SSE4.1+ v_select 'mask' is restricted to these values only: 0 or ~0 (0xff/0xffff/etc) mask in accuracy test is updated.	7 years ago
Alexander Alekhin	4a297a2443	ts: refactor OpenCV tests - removed tr1 usage (dropped in C++17) - moved includes of vector/map/iostream/limits into ts.hpp - require opencv_test + anonymous namespace (added compile check) - fixed norm() usage (must be from cvtest::norm for checks) and other conflict functions - added missing license headers	7 years ago
Alexander Alekhin	a5cd62f7bf	core(perf): refactor kmeans test - don't use RNG for "task size" parameters (N, K, dims) - add "good" kmeans test data (without singularities: K > unique points)	7 years ago
Sayed Adel	fd0ac962fb	core: replace raw intrinsics with universal intrinsics in copy.cpp - use universal intrinsic instead of raw intrinsic - add performance check for Mat::copyTo/setTo with mask	7 years ago
