Matlab-Extract data points from figure

[koubaros]

I would like to extract the experimental data points (x, y coordinates) from a figure that i recently found in a paper. Is there any way of using matlab to scan the document and by some way (image processing maybe?) to get the coordinates of the points?

I know this is no trivial task so any redirections, hints tips would be greatly appreciated.

There are a number of programs that do that. Tracer is one.
