摘要：Image binarization is the procedure of separating pixel values into two parts, black as foreground and white as background. Inbinarization document image is converted into binary image using thresholding techniques. Many binarization algorithms have beenproposed for different types of degraded document images. The main objective of image enhancement is to modify attributes of an image tomake it more suitable for a given task . To remove the noise and improve the quality of the document binarization techniques are used.Thresholding is one of such binarzation technique which is used for this purpose. Thresholding is further divided into the global and localthresholding techniques. In the document with uniform contrast delivery of background and foreground, global thresholding has beenfound to be best technique. Local thresholding , is an approach for the situations in which single value thresholding does not yield properresult, to overcome this a hybrid approach is introduced which is a combination of local with Otsu’s thresholding
