Alexander Alekhin	cbfd38bd41	core: rework code locality - to reduce binaries size of FFmpeg Windows wrapper - MinGW linker doesn't support -ffunction-sections (used for FFmpeg Windows wrapper) - move code to improve locality with its used dependencies - move UMat::dot() to matmul.dispatch.cpp (Mat::dot() is already there) - move UMat::inv() to lapack.cpp - move UMat::mul() to arithm.cpp - move UMat:eye() to matrix_operations.cpp (near setIdentity() implementation) - move normalize(): convert_scale.cpp => norm.cpp - move convertAndUnrollScalar(): arithm.cpp => copy.cpp - move scalarToRawData(): array.cpp => copy.cpp - move transpose(): matrix_operations.cpp => matrix_transform.cpp - move flip(), rotate(): copy.cpp => matrix_transform.cpp (rotate90 uses flip and transpose) - add 'OPENCV_CORE_EXCLUDE_C_API' CMake variable to exclude compilation of C-API functions from the core module - matrix_wrap.cpp: add compile-time checks for CUDA/OpenGL calls - the steps above allow to reduce FFmpeg wrapper size for ~1.5Mb (initial size of OpenCV part is about 3Mb) backport is done to improve merge experience (less conflicts) backport of commit: `65eb946756`	4 years ago

Zhuo Zhang	743099f9f9	Merge pull request #19521 from zchrissirhcz:3.4-fix-core-module-android-arm64-build * fix core module android arm64 build * fix core module android build when neon is off When building for Android ARM platform, cmake with `-D CV_DISABLE_OPTIMIZATION=ON`, the expected behavior is not using ARM NEON, using naive computation instead. This commit fix the un-expected compile error for neon intrinsincs.	4 years ago
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
Vincent Rabaud	847b16fb76	Disable thread sanitization when CV_USE_GLOBAL_WORKERS_COND_VAR is not set. This fixes #19463	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
