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 |
