[vox-tech] extraction of numbers from graph images

[Dylan Beaudette]

Hi,

i know that I have heard of something like this in the past- even perhaps a 
linux program...

say i have a scanned graph, with legible axis - is there a program that with a 
little help can extract the coordinate data from the graph?

Cheers,
