PR #2968:cce2d998578f9cFixed bug which caused crash of GPU version of feature matcher in stitcher The bug caused crash of GPU version of feature matcher in stitcher when we use ORB features. PR #3236:5947519Check sure that we're not already below required leaf false alarm rate before continuing to get negative samples. PR #3190 fix blobdetector PR #3562 (part):82bd82eTBB updated to 4.3u2. Fix for aarch64 support. PR #3604 (part):091c7a3OpenGL interop sample reworked not ot use cvconfig.h PR #3792:afdf319Add -L for CUDA libs path to pkg-config Add all dirs from CUDA_LIBS_PATH as -L linker options to OPENCV_LINKER_LIBS. These will end up in opencv.pc. PR #3893:122b9f8Turn ocv_convert_to_lib_name into a function PR #5490:ec5244afixed memory leak in findHomography tests PR #5491:0d5b739delete video readers PR #5574 PR #5202
