Hi everyone,
is there a way to analyze the frequencies of a frame separately (like fft3dfilter gives the option to process 4 frequencies with different sigma values) so that I can set the options in fft3dfilter on basis of "knowledge" and not by guessing? I, for instance, don't know what frequency the noise, that I see, is and so can only do the denoising by try-and-error.
More general: Is there a way to analyze noise, so that I can tell, whether it's luma or chroma, which channel of luma and then which frequency?
Thanks for help!
