Diagrams Recognition

Hi dangos!

Does anybody know about any software to recognize go diagrams in images and convert them to SGF files? I'm not able to find any...

I don't suppose it's a difficult task as it's possible to recognize more complicated patterns (like human faces). I want to write some script, if I don't anything. I just don't want to reinvent wheel.

Thanks in advance for you answers:)

I know no program that does recognize diagrams. I assume you have a printed diagram with move-numbers you want to recognize. There are some programs which recognize the board-state in a photo, and some that can recognize the board-state in a screenshot of a typical go program.

Well, I have book with go diagrams (tsumego). I don't need sgf's with solutions (diagrams with move-numbers), just initial board-state.

Do you know names of those programs you are talking about?

A webcam based programs:

My go program has a screenshot based recorder. But it won't directly work for what you need. In particular it requires a brown background as the board. But you can use parts of the source in your own program if you want that.

I just read on SL that Compogo can do this.
