[HAL RVV] reuse atan | impl cart_to_polar | add perf test #27000 Implement through the existing `cv_hal_cartToPolar32f` and `cv_hal_cartToPolar64f` interfaces. Add `cartToPolar` performance tests. cv_hal_rvv::fast_atan is modified to make it more reusable because it's needed in cartToPolar. **UPDATE**: UI enabled. Since the vec type of RVV can't be stored in struct. UI implementation of `v_atan_f32` is modified. Both `fastAtan` and `cartToPolar` are affected so the test result for `atan` is also appended. I have tested the modified UI on RVV and AVX2 and no regressions appears. Perf test done on MUSE-PI. AVX2 test done on Intel(R) Xeon(R) Gold 6140 CPU @ 2.30GHz. ```sh $ opencv_test_core --gtest_filter="*CartToPolar*:*Core_CartPolar_reverse*:*Phase*" $ opencv_perf_core --gtest_filter="*CartToPolar*:*phase*" --perf_min_samples=300 --perf_force_samples=300 ``` Test result between enabled UI and HAL: ``` Name of Test ui rvv rvv vs ui (x-factor) CartToPolar::CartToPolarFixture::(127x61, 32FC1) 0.106 0.059 1.80 CartToPolar::CartToPolarFixture::(127x61, 64FC1) 0.155 0.070 2.20 CartToPolar::CartToPolarFixture::(640x480, 32FC1) 4.188 2.317 1.81 CartToPolar::CartToPolarFixture::(640x480, 64FC1) 6.593 2.889 2.28 CartToPolar::CartToPolarFixture::(1280x720, 32FC1) 12.600 7.057 1.79 CartToPolar::CartToPolarFixture::(1280x720, 64FC1) 19.860 8.797 2.26 CartToPolar::CartToPolarFixture::(1920x1080, 32FC1) 28.295 15.809 1.79 CartToPolar::CartToPolarFixture::(1920x1080, 64FC1) 44.573 19.398 2.30 phase32f::VectorLength::128 0.002 0.002 1.20 phase32f::VectorLength::1000 0.008 0.006 1.32 phase32f::VectorLength::131072 1.061 0.731 1.45 phase32f::VectorLength::524288 3.997 2.976 1.34 phase32f::VectorLength::1048576 8.001 5.959 1.34 phase64f::VectorLength::128 0.002 0.002 1.33 phase64f::VectorLength::1000 0.012 0.008 1.58 phase64f::VectorLength::131072 1.648 0.931 1.77 phase64f::VectorLength::524288 6.836 3.837 1.78 phase64f::VectorLength::1048576 14.060 7.540 1.86 ``` Test result before and after enabling UI on RVV: ``` Name of Test perf perf perf ui ui ui orig pr pr vs perf ui orig (x-factor) CartToPolar::CartToPolarFixture::(127x61, 32FC1) 0.141 0.106 1.33 CartToPolar::CartToPolarFixture::(127x61, 64FC1) 0.187 0.155 1.20 CartToPolar::CartToPolarFixture::(640x480, 32FC1) 5.990 4.188 1.43 CartToPolar::CartToPolarFixture::(640x480, 64FC1) 8.370 6.593 1.27 CartToPolar::CartToPolarFixture::(1280x720, 32FC1) 18.214 12.600 1.45 CartToPolar::CartToPolarFixture::(1280x720, 64FC1) 25.365 19.860 1.28 CartToPolar::CartToPolarFixture::(1920x1080, 32FC1) 40.437 28.295 1.43 CartToPolar::CartToPolarFixture::(1920x1080, 64FC1) 56.699 44.573 1.27 phase32f::VectorLength::128 0.003 0.002 1.54 phase32f::VectorLength::1000 0.016 0.008 1.90 phase32f::VectorLength::131072 2.048 1.061 1.93 phase32f::VectorLength::524288 8.219 3.997 2.06 phase32f::VectorLength::1048576 16.426 8.001 2.05 phase64f::VectorLength::128 0.003 0.002 1.44 phase64f::VectorLength::1000 0.020 0.012 1.60 phase64f::VectorLength::131072 2.621 1.648 1.59 phase64f::VectorLength::524288 10.780 6.836 1.58 phase64f::VectorLength::1048576 22.723 14.060 1.62 ``` Test result before and after modifying UI on AVX2: ``` Name of Test perf perf perf avx2 avx2 avx2 orig pr pr vs perf avx2 orig (x-factor) CartToPolar::CartToPolarFixture::(127x61, 32FC1) 0.006 0.005 1.14 CartToPolar::CartToPolarFixture::(127x61, 64FC1) 0.010 0.009 1.08 CartToPolar::CartToPolarFixture::(640x480, 32FC1) 0.273 0.264 1.03 CartToPolar::CartToPolarFixture::(640x480, 64FC1) 0.511 0.487 1.05 CartToPolar::CartToPolarFixture::(1280x720, 32FC1) 0.760 0.723 1.05 CartToPolar::CartToPolarFixture::(1280x720, 64FC1) 2.009 1.937 1.04 CartToPolar::CartToPolarFixture::(1920x1080, 32FC1) 1.996 1.923 1.04 CartToPolar::CartToPolarFixture::(1920x1080, 64FC1) 5.721 5.509 1.04 phase32f::VectorLength::128 0.000 0.000 0.98 phase32f::VectorLength::1000 0.001 0.001 0.97 phase32f::VectorLength::131072 0.105 0.111 0.95 phase32f::VectorLength::524288 0.402 0.402 1.00 phase32f::VectorLength::1048576 0.775 0.767 1.01 phase64f::VectorLength::128 0.000 0.000 1.00 phase64f::VectorLength::1000 0.001 0.001 1.01 phase64f::VectorLength::131072 0.163 0.162 1.01 phase64f::VectorLength::524288 0.669 0.653 1.02 phase64f::VectorLength::1048576 1.660 1.634 1.02 ``` ### 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 - [ ] The PR is proposed to the proper branch - [ ] There is a reference to the original bug report and related work - [ ] 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 |

This folder contains libraries and headers of a few very popular still image codecs
used by imgcodecs module.
The libraries and headers are preferably to build Win32 and Win64 versions of OpenCV.
On UNIX systems all the libraries are automatically detected by configure script.
In order to use these versions of libraries instead of system ones on UNIX systems you
should use BUILD_<library_name> CMake flags (for example, BUILD_PNG for the libpng library).

Enable BUILD_JPEG_TURBO_DISABLE=ON to force using of libjpeg (this option is removed in OpenCV 4.0).
SIMD instructions are enabled by default. Use ENABLE_LIBJPEG_TURBO_SIMD to control SIMD instructions.
