SharpEye is an optical music recognition (OMR) program that has an interactive graphical environment for editing the symbolic music notation extracted from scanned music.

	Start SharpEye in the Lab by clicking on the taskbar icon which looks like a cyan/black wholenote with a sharp in front of it ([[File:Sharpeyeicon.png]]) in windows, or type "<tt>sharpeye</tt>" in the terminal in OS X. Music can be scanned directly from SharpEye using the "Aquire" option in the File menu, or you can scan with a separate program and choose "Open Image" option in the File menu to load the graphic music. When processing several pages of music, it is more efficient to first scan with the [[Epson GT-15000 Scanner]] in the lab, and then process the scanned images in batch mode within SharpEye.
