This paper presents a novel approach to binarizing document images. All blocks with individual background intensity values in a document image are first extracted using a two-stage extraction procedure. Then, the intensity distribution of each block is calculated to determine the variation ranges of background intensity. For each extracted block, interior pixels whose intensity values fall within these ranges are regarded as background pixels. For those pixels outside all extracted blocks, Otsu… CONTINUE READING
