Pierre Chatelier ebb6915e58 Merge pull request #21645 from chacha21:applyColorMap_8UC1_optimized ... Optimize cv::applyColorMap() for simple case * Optimize cv::applyColorMap() for simple case PR for 21640 For regular cv::Mat CV_8UC1 src, applying the colormap is simpler than calling the cv::LUT() mechanism. * add support for src as CV_8UC3 src as CV_8UC3 is handled with a BGR2GRAY conversion, the same optimized code being used afterwards * code style rely on cv::Mat.ptr() to index data * Move new implementation to ColorMap::operator() Changes as suggested by reviewer * style improvements suggsted by reviewer * typo * tune parallel work * better usage of parallel_for_ use nstripes parameter of parallel_for_ assume _lut is continuous to bring faster pixel indexing optimize src/dst access by contiguous rows of pixels do not locally copy the LUT any more, it is no more relevant with the new optimizations		3 years ago
