Francesco Petrogalli	6ee23c9b85	Merge pull request #19486 from fpetrogalli:dotprod_fast-3.4 * [hal][neon] Optimize the v_dotprod_fast intrinsics for aarch64. On Armv8 in AArch64 execution mode, we can skip the sequence v<op>_<ty>(vget_high_<ty>(x), vget_high_<ty>(y)) in favour of v<op>_high_<ty>(x, y) This has better changes for recent compilers to use less data movement operations and better register allocation. See for example: https://godbolt.org/z/bPq7vd * [hal][neon] Fix build failure on armv7. * [hal][neon] Address review comments in PR. PR: https://github.com/opencv/opencv/pull/19486 * [hal][neon] Define macro to check for the AArch64 execution state of Armv8. * [hal][neon] Fix macro definition for AArch64. The fix is needed to prevent warnings when building for Armv7.	4 years ago

Pavel Rojtberg	6c1a433c4c	python: also catch general c++ exceptions they might be thrown from third-party code (notably Ogre in the ovis module). While Linux is kind enough to print them, they cause instant termination on Windows. Arguably, they do not origin from OpenCV itself, but still this helps understanding what went wrong when calling an OpenCV function.	4 years ago

Jojo R	12b8d542b7	norm.cpp(normL2Sqr_): improve performance of pipeline The most of target machine use one type cpu unit resource to execute some one type of instruction, e.g. all vx_load API use load/store cpu unit, and v_muladd API use mul/mula cpu unit, we interleave vx_load and v_muladd to improve performance on most targets like RISCV or ARM.	4 years ago
