Abstract : In this paper, a new approach to binarize grey-level document images is proposed. The method combine a global and a local approaches. First, we provide the edges of the image, and next, from the edges we make a quadtree decomposition of the image. On each area of the image, a local threshold is computed and applied to all the pixels belonging to the region under consideration.
