looking for a good edge mask filter

[unclescoob]

I can't remember which function does this, but I'm trying to mask my edges during filtration.

Anyone can lead me to the right path on this one?

THanks

masktool: EdgeMask()
mt_masktools: mt_edge()

Thanks. I've tried this before and it just shows a green/black flashy screen. I once became familiar with this function and just forgot. Can you please post a sample? For instance, converting the image to grayscale but protecting the lines (just so I can see how it works).

Thanks.

How to use mt_edge() to make a crude spacial noise reduction filter that retains sharp edges:

edges = mt_edge() # build an edge mask
mt_merge(blur(1.0), last, edges) # overlay a blurred image except at sharp edges

Thanks. Heaven forbid the stupid retarded documentation that comes with the function posts samples

MaskTools has several examples: http://avisynth.nl/index.php/MaskTools

can you please show me a sample script of how I would apply grayscale to the image, but protect a portion around the edges from it? So I can see a bit of the color and have an idea how to work the script

It's easier to use Overlay() for that purpose:

edges = mt_edge() # build an edge mask
Overlay(GreyScale(last), last, mask=edges)  # overlay a grey image except at sharp edges

You may want to expand and/or blur the mask:

edges = mt_edge().mt_expand().Blur(1.0) # build an edge mask

Ok, I'll try this when I get home.

I don't hear from Sanlyn these days.
