I need to correct a paper containing graphs saved as bitmap images. Those

some way to "undo" the graph and get back the curves ?
I can take the image, apply a differentiator, check for regions of high
contrast, and map that region back to values. But if some automatic tool
could do it quickly and without error, it would be better.
There's Engauge
as well as some excellent web based ones (Tatsuro's email)
