cudawarped	7539abecdb	cuda: add python bindings to allow GpuMat and Stream objects to be initialized from raw pointers	2 years ago
Sean McBride	27e10efa66	Use std::atomic<bool> as it's necessary for correct thread safety Now that C++11 is required, we can unconditionally use std::atomic in this case, which is more correct.	2 years ago
Pierre Chatelier	6dd8a9b6ad	Merge pull request #13879 from chacha21:REDUCE_SUM2 add REDUCE_SUM2 #13879 proposal to add REDUCE_SUM2 to cv::reduce, an operation that sums up the square of elements	2 years ago
Sean McBride	58e4a880a2	Deprecated convertTypeStr and made new variant that also takes the buffer size This allows removing the unsafe sprintf.	2 years ago
Sean McBride	47bea69322	Merge pull request #23055 from seanm:sprintf2 * Replaced most remaining sprintf with snprintf * Deprecated encodeFormat and introduced new method that takes the buffer length * Also increased buffer size at call sites to be a little bigger, in case int is 64 bit	2 years ago
eplankin	fd8b346c3e	Merge pull request #23443 from eplankin:3.4 * Update IPPICV binaries (20230330) * Revert "core(IPP): disable some ippsMagnitude_32f calls" This reverts commit `8069a6b4f8`. * Reverted changes in norm() and count_non_zero()	2 years ago
Christian Henkel	c9e42c5050	two typos	2 years ago
Yannis Guyon	bf29a4d746	Avoid double-checked locking with TSAN in parallel Omit the first check of the double-checked locking pattern in recordException() in parallel.cpp when CV_THREAD_SANITIZER is defined. This should only slow recordException() down when the thread sanitizer is used, and avoids the TSAN data race warning.	2 years ago

fengyuentau	34a0897f90	add cv::flipND; support onnx slice with negative steps via cv::flipND	2 years ago
Vincent Rabaud	7463e9b8bb	Even faster CV_PAUSE on SkyLake and above. No need to loop as RDTSC is 3/4 times faster than _mm_pause.	2 years ago

Sean McBride	5b23752205	Replaced incorrect double checked locking with a static Thread Sanitizer identified an incorrect implementation of double checked locking. Replaced it with a static, which therefore can only be created once.	3 years ago
Vincent Rabaud	fc28ba3156	Merge pull request #21594 from vrabaud:3.4_msan * Fix harmless MSAN error. This is similar to https://github.com/opencv/opencv/pull/21527 A macro is also created to simplify the code. * Declare fallback only once.	3 years ago

Ed Martin	dc29632d4e	Fallback to vaCreateImage + vaPutImage/vaGetImage when vaDeriveImage fails Per intel docs for libva, when vaDeriveImage fails vaCreateImage + vaPutImage should be tried. This is important as mesa with AMD HW will always fail because the image is interlaced so a indirect method must be used to get the surface to/from and image Fixes https://github.com/opencv/opencv/issues/21536	3 years ago
Vincent Rabaud	b5b52afd35	Merge pull request #21527 from vrabaud:3.4_msan * Fix wrong MSAN errors. Because Fortran is called in Lapack, MSAN does not think the memory has been written even though it is the case. MSAN does no support well cross-language memory analysis. * Make a dedicated check.	3 years ago
