What is Optical Glyph Recognition (OGR)?

Hello Fabrizio, OGR Team, and everyone on the SignWriting List -

Thank you for your project, which I am sure will be a useful tool for the SignWriting Community… and thank you for your patience waiting for me to provide you with some handwritten SignWriting documents… I also want to thank the writers of Tunisian Sign Language for providing these documents for us -

On Facebook, the "Forum Tunisien de SignWriting" is very active, and today they posted handwritten documents written by students in Tunisian Sign Language… I assume this is what you need, Fabrizio, for your research? Please see attached documents…

You can see other amazing works, art and documents written in Tunisian Sign Language, on Facebook at the Forum Tunisien de SignWriting:  https://www.facebook.com/forumtunisiendesingwriting

Our goal is to make them digital, to empower their diffusion, and to ensure a long-lasting existence for them.
