I've been doing some experiments in using Wavelet filters
for video noise reduction and I was really happy with the
results. I was thinking that maby replacing (or extending)
the FFT with the Wavelet Transform would be much
better, because of its better time resolution for high
frequencies without loosing overall precision for low
frequencies.
I've also tried to use FFT de-noise in 4 passes, each
operating at different frequency range with larger window
for low freqs and smaller for high frequencies and I found
out, that the results are quite nice.
