Determining which are the text and graphic regions in an image

Question

I dont know whether should I post this question here or not? But if someone knows it, please answer?

What are the algorithms for determining which region in an image is text and which one is graphic? Means how to separate such regions? (figure or diagram)

Answer 1

Most OCR software, e.g., Ocropus, support layout analysis, which is what you need.

Mao, Rosenfeld & Kanungo (2003) Document structure analysis algorithms: a literature survey provides a fairly recent survey of layout analysis algorithms.
