From the developer: ""The UN-SCAN-IT software allows you to automatically convert scanned graphs to (x, y) data at Full Scanner Resolution!
UN-SCAN-IT works with any full page scanner, hand scanner, or other image input device to digitize strip charts, instrumental output, old graphs, published graphs, etc. In addition to the many digitizing features, UN-SCAN-IT also integrates peak areas, smooths data, takes derivatives, re-scales graphs, and exports (x, y) ASCII data for use in other software programs.""
Note: This program costs $345 to register and the demo allows you to test digitize your own image or digitize an included sample image.
