Yuya Unno	500c55a808	Merge pull request #25122 from unnonouno:pqueue Use std::priority_queue in inpaint function for performance improvement #25122 In `cv::inpaint` implementation, it uses a priority queue with O(n) time linear search. For large images it is very slow. I replaced it with C++'s standard library `std::priority_queue`, that uses O(log(n)) algorithm. In my use case, it is x10 faster than the original. ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [ ] There is a reference to the original bug report and related work - [x] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [ ] The feature is well documented and sample code can be built with the project CMake	9 months ago
Marco Feuerstein	bc8d494617	Merge pull request #22959 from feuerste:parallel_mertens Parallelize implementation of HDR MergeMertens. * Parallelize MergeMertens. * Added performance tests for HDR. * Ran clang-format. * Optimizations. * Fix data path for Windows. * Remove compiiation warning on Windows. * Remove clang-format for existing file. * Addressing reviewer comments. * Ensure correct summation order. * Add test for determinism. * Move result pyramid into sync struct. * Reuse sync for first loop as well. * Use OpenCV's threading primitives. * Remove cout.	2 years ago
Jakub Golinowski	9f1218b00b	Merge pull request #11897 from Jakub-Golinowski:hpx_backend * Add HPX backend for OpenCV implementation Adds hpx backend for cv::parallel_for_() calls respecting the nstripes chunking parameter. C++ code for the backend is added to modules/core/parallel.cpp. Also, the necessary changes to cmake files are introduced. Backend can operate in 2 versions (selectable by cmake build option WITH_HPX_STARTSTOP): hpx (runtime always on) and hpx_startstop (start and stop the backend for each cv::parallel_for_() call) * WIP: Conditionally include hpx_main.hpp to tests in core module Header hpx_main.hpp is included to both core/perf/perf_main.cpp and core/test/test_main.cpp. The changes to cmake files for linking hpx library to above mentioned test executalbles are proposed but have issues. * Add coditional iclusion of hpx_main.hpp to cpp cpu modules * Remove start/stop version of hpx backend	6 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
