Remap on CUDA
Remap option can fix lens distortions, rotations and also can correct color differences between channels at the same time. We can do remap for every image component either separately or alltogether.
We've implemented remap feature on GPU and it's working very fast. To see live benchmarks, we would suggest to download Fast CinemaDNG Processor software to see quality and performance.
Here you can see our solution for FFmpeg Remap Filter which has the same code, but is intended for streaming applications in connection with FFmpeg or libav.
