Music Note Recognition

The process of optical music recognition, converting a music sheet into notes and pitches in a digital representation, resembles the process of optical character recognition. It involves a lot of steps from the broad spectrum of image processing. Optical music recognition includes the steps from pre-processing the input image, to classifying extracted musical features into the output that is a string representation of the notes.
