Hello,

Could anyone explain the parameters and algorithm of Smooth - Patch Based?

- Spatial Variance - Is it the h Parameter of the Non Local Means?
- Patch Variance - The original Non Local Means used Weighing Window for patches, is it the Variance of the Gaussian Window?
- Patch Size - Is it the size or the radius of the patch?
- Lookup Size - I guess this is the Search Window size. Again, is it Radius or size?
- Patch Smoothness - What is that?
- Fast Approximation - What is the approximation used?
- Iterations - This is clear :-).
- Spatial Overlap - What does it mean?

Is it based on Non Local Means?

What kind of Non Local Means is it?

Is it the [IPOL Non Local Means](http://Non-Local Means Denoising)?

Thank You.
