A new method is presented for adaptive document image binarization, where the page is considered as a collection of subcomponents such as text, background and picture. The problems caused by noise, illumination and many source type related degradations are addressed. The algorithm uses document characteristics to determine (su #ace) attributes, ofen used in document segmentation. Using characteristics analysis, two new algorithms are applied to determine a local threshold for each pixel. An… CONTINUE READING
