Solution 1

First of all, please see the open-source AForge.NET:[^],[^].

Alternatively, consider Emgu CV:[^].

This is a is a cross platform .Net wrapper to the OpenCV image processing library; and OpenCV is an open-source C++ computer vision library:[^],[^].


There are also some works closer to ORM. More exactly, it's OCR, but you can use it for OMR purposes ([^]).

Please see:[^],[^].

Unfortunately, I must warn you: I never found any Open-Source OCR solutions which would be good enough. There are few CodeProject solutions I like, but, to best of knowledge, they are all incomplete, would need serious amount of work to make a working application out of them.

Please see the CodeProject articles:

Neural Network OCR[^],
Creating Optical Character Recognition (OCR) applications using Neural Networks[^],
Neural Network Classifier[^],
A C# Project in Optical Character Recognition (OCR) Using Chain Code[^],
Unicode Optical Character Recognition[^],
Hebb neural network[^],
Backpropagation Artificial Neural Network in C++[^],
OCR Line Detection[^].

I have to warn you: some of these works are very good, much better compared to the quality I complained about above, but none of these works is completed into a ready-to-use application. They all require considerable amount of work to complete to such level.

Maybe there are newer projects I'm not familiar with; so it would not hurt if you do your own search in CodeProject and elsewhere. Please, if you find something good, please reply in the comment to this answer.

Good luck,
