Non-Local Mean based advanced 2D-NR with noise estimation:
- preserving details better than conventional methods(mean -, bilateral edge preserving filter etc.)
- strong noise reduction near a result of 3D-NR with minimized H/W resources
- limitations : loss of some fine details(see hair details of the right-below result image)
