An artifact removal technique for skew corrected images

摘要

A digital image processing method and system is adapted to remove diagonally disposed artifacts such as lines, dots, dashes etc., from a scanned skewed corrected document or image. The system and method converts a captured skew corrected image into first and second binary images and generates a map indicative of a difference between the first and second binary images. Black pixels in the map are projected based on a skew angle of the image to form a projection profile, and an image based on the map, detected peaks in the projection profile and the pixels is created. <IMAGE>
