Noise related #17

Hi Rys: You said "FSR's algorithm can potentially exacerbate high frequency input". So does the following steps theoretically help(I don't have access to the render pipe, only the final render result):

  1. Apply Fourier Transform on the target to remove high frequency part
  2. Apply FSR
  3. put high frequency part back to the target

At least use the Fourier analysis like the paper above to check Spectral Energy Leakage form padding, filter kernel.
Maybe then try to "noise shaping" like in audio aplications.
