What you want would be quite cool to have but is hard to implement :-)
Some video effect software got tools to do this, 
but they cost quite much, like Adobe After Effects for example.
Do a search for rotoscoping software.

To do this in Squeak you could maybe put a Polygon morph on top of the 
video frame and outline the character. If you hooked the Polygon morph
up to
a timeline you could step trough the frames and move your outline accordingly.
Or if you you could use a pixel tracing algorithm that trace
the pixels under the polygon vertices to move the outline accordingly to
the character.
I would like to have such a tool :-) Let me know if you want help to implement.
