Is this a research topic of yours or do you just want to solve the
problem? If you just want to solve it, I would look into
http://potrace.sourceforge.net/
which seem to do what you are looking for (I've used it successfully
with Inkscape in the past).
If you are doing this as a research topic, then I guess Octave is a fine
platform. You can easily get the images into Octave using 'imread'.
Things like edges can be detected with the 'edge' function from the
'image' package. It shouldn't be hard to trace edges (I think we have a
function for this in the 'image' package, but I forgot its name). For
starters you can just create the SVG by plotting your traced curves and
print them into SVG files.
