Smoothing effect

[badabou]

Hello,

I try to reproduce this effect with imagemagick but I do not find a solution.

Is this possible?

Thank you

You may also like to try using a raster to vector and back to raster conversion!

See IM examples...
http://www.imagemagick.org/Usage/transform/#edge_vector
and
http://www.imagemagick.org/Usage/draw/#svg_output

It should work well as you have already eliminated anti-aliasing pixels that will often confuse a tool like "autotrace".

NOTE IM does have the ability to make direct use of autotrace when either reading or writing images like this. See the above link for details.


You may also like to clean up and smooth speckles before using autotrace (or median) by using Morphology Operators to smooth the edges a little.
