Abstract:

An efficient system and method for reliably identifying guidelines, ruled lines, and the like, in images of text, and distinguishing those portions of such lines which touch or intersect character strokes in the image. The system provides for removal of guideline segments between character strokes without deleting character strokes. The system operates effectively on both machine printed and hand formed text. An image of text has most characters separated for more effective subsequent OCR processing, despite the presence of guidelines connecting the characters.
