  • Test of 4,5,10 and 11 from CUDA_ImgProc/CvtColor.LBGR2Lab changes behvior based on runtime.
  • It has non-deterministic behavior
  • Same for CUDA_ImgProc/CvtColor.LRGB2Lab and CUDA_ImgProc/CvtColor.LBGRA2Lab4
  • The test CUDA_ImgProc/CvtColor.LRGBA2Lab4 doesn't exist, so anything from LBGR to Lab space has some non-deterministic behavior
