[Insight-users] Vectorizing 2D picture

[Torsten Rohlfing]

Fabrice --

there is very good software outside of ITK that might help you:

potrace - *potrace*.sourceforge.net
autotrace - *autotrace*.sourceforge.net

In each case, you need to convert your DICOM image to something more 
generic, like TIFF or PNG for example. ITK should have a tool for that.

The output of the tracing tools will be SVG, EPS, or similar, so again, 
you may have to convert to get the vectorized data into the next software.

I have used both tools, and they work very nicely. Personally, I prefer 
potrace since its output is slightly more convenient to post-process 
with an SVG editor. Autotrace often combines distant, separate objects 
in the same polygon object, and that's a bit of a pain when you want to 
delete something in the vectorized image.

Best,
  Torsten
