In the case you are going to use Glyph Recognition library in your application, the information and sample codes below may be quite useful to give quick direction and some results.
The first thing to do is to add reference to AForge.Vision.GlyphRecognition.dll assembly to your project, which can be found in binary distribution of the GRATF project or built from sources. Also you will need to add references to AForge.dll, AForge.Imaging.dll and AForge.Math.dll (part of AForge.NET framework), since those are used by Glyph Recognition library. In the case if you work with video files, cameras, etc., you may need adding some other references as well.
