Line removal technique for document and non document images

In this paper, a novel technique for the removal of both horizontal and vertical lines in the document images are presented using shift, difference and coordinate logic operations. The method is also employed in the non-document images to remove the lines and to detect the edges. The proposed method shows promising results than the conventional methods using morphological operations for edge detection. The performance of the proposed method is demonstrated by considering printed, handwritten document and non-document gray level as well as coloured images.
