Abstract

A clean document image is necessary for many tasks such as page layout analysis, OCR system and so on. In case of poor document image, these tasks may not be finished with satisfaction. This paper proposes a simple approach for extracting text lines and segmenting image regions from a textual and non-textual regions mixed color document image with uneven shading. The algorithm removes the uneven shading first and then computes Canny edges. By analyzing connected components heuristically, the text regions and image regions contained in the given document image are extracted and segmented. Finally a clean document image is obtained using a trivial synthesis method. Our experimental results demonstrate that the proposed approach performs plausible.
