Consensus on the problem is that there are ways to "sort of" do what KT asked for, but there are no magic solutions that will take all of the work out of it.

MIDIScan and SharpEye are the two most commonly cited programs for conversion of scans to some form of notation. They work - up to a point, but will not eliminate all of the "handwork."

There is a lot of related information on this subject in previous threads. Anyone interested might want to take another look at:

Mudcat MIDI Guide
PC Music Editing Software
Music Annotation Software

A specific Summary on Annotation Software in the last thread above may be helpful, although I'd certainly recommend reading the whole thread.
