Tune
the edges detection slider to separate edges from surfaces without
including noise in edges. The black and white images below show the
result effect, for 3 values on 3 parts of the demo image.
Originals
Surfacing 50 : not enough, significant edges do not appear
Edges detection 80 : correct, some unwanted details start to appear
Edges detection 86 : too much, a lot of unwanted details appear
Advanced tuning : depending on the kind of noise you have, you can play with the "Chroma
modes", to avoid chroma artifact to be considered as images details.
