many noise filters (much simpfied) somehow average the pixel and it's neighboars
now what if instead of just using this average ast eh new values for the pixel we pick the one of the 9 pixels that is closest to that average and use it as the new value
example:
1 50 10
45 124 5
230 55 123
a simple blur: would turn the 124 into 71
my example-filter (already avaible) would pick the closest value to 71 in the "neighberhood", in this case 55
with simple blur this is a pretty bad filter
but with combined with better denoisers this might give good results
what do you guys think??
thx
