Binarization is usually the first step in document analysis and recognition. This paper propose a new binarization technique base on local thresholding using information from edge pixel. Indeed, an edge represent a rupture between foreground and background elements. It is then reasonable establishing a local threshold on each edge pixel. An average of this edge-based local threshold is used to classify each pixel as either foreground or background. This averaging process can be done rapidly… CONTINUE READING
