Text - Image Separation in Devanagari Documents

In this paper we present a top-down, projection-profile based algorithm to separate text blocks from image blocks in a Devanagari document. We use a distinctive feature of Devanagari text, called Shirorekha (Header Line) to analyze the pattern produced by Devanagari text in the horizontal profile. The horizontal profile corresponding to a text block possesses certain regularity in frequency, orientation and shows spatial cohesion. The algorithm uses these features to identify text blocks in a document image containing both text and graphics.
