Perspective distortion always occurs while scanning thick, bound documents. This distortion mainly causes two sources of degradation for the scanned grayscale image – i) shade along the ‘spine’ of the book, and ii) warp of the words in the shade. In this paper, we propose a restoration system to solve these two problems. Our system first produces a vertical projection profile to detect which side of the image the shade lies on, and a run-length method is used to find the boundary between the… CONTINUE READING
