There is no OCR toolbox. You can find OCR algorithms here: http://iris.usc.edu/Vision-Notes/bibliography/contentschar.html#OCR,%20Document%20Analysis%20and%20Character%20Recognition%20Systems Pick one and code it up.

To project, you can use this

verticalProjection = sum(theImage, 2);
horizontalProjection = sum(theImage, 1);

You can use mean instead of sum if you want.
