What an efficient denoise filter!
I'm very curious about the filter coefficients, which look a lot like the CSF frequency sensitivity curve.
The monotonically increasing part of the first half of the curve ensures that the compensation value is less than the difference; the monotonically decreasing part gradually reduces the compensation value to prevent blurring the edge. I don't know if the above understanding is correct?
Can you please share how this coefficient curve is designed?
Thanks a lot!
