Optical Music Recognition System in Rust

🚧 🚧 🚧 🚧 🚧 🚧

Given an image of some typeset sheet music, extract a semantic representation of it:

• Input format: 8-bit grayscale raster image in a format ImageMagck can read.
• Output format: To be determined. Music XML? Cleaned up SVG?

Goals for the code:

• Fast
• Minimal Dependencies
• Perfect performance on a well defined subset of LilyPond output

Personal Goals:

• Learn Rust
• Maintain some of my Computer Vision chops
• Make the poor quality scans of sheet music on todotango at least print decently on my girlfriend's poor quality printer
• Maybe someday do automatic transcription to alternative music notations

Non-Goals at this time:

• Supporting handwritten music
• Ports to Mac, Windows

Disclaimer

This code is being developed as a hobby, in a language that I am still learning, and which has not even hit 1.0. I am only sharing it on github because I develop ~everything in the open. I have no expectaton that it will be useful any time soon, and you shouldn't either. Run at your own risk!

Status

This is what I have actually implemented so far:

• Loading of images directly from .pgm files using pure Rust
• Loading anything image magick can load, provided it is installed
• Currently hacking around with geometry primitives

Dependencies

• The Rust Compiler and Standard Library; I am tracking the Nightly versions until rust 1.0
• Runtime dependency on image magick's "convert" utility for loading images
