Ash, I don't know if marwa ever did. However, if you're interested in a thresholding method (which marwa is NOT ) then you can see my attached demo.

You can use manual tracing. See attach demos for imfreehand().

Sorry, no.
Perhaps I can help if you give something much, much smaller to ask about rather than programming up a whole algorithm, which could take hours to months to do.

Lots of preexisting packages out there that are free for acadmic use:
SPM (which runs on matlab)
FSL (compiled c++ runs on LINUX and MAC OS X)
ANTs (runs on LINUX and MAC OS X)
Googling will get you the links.
