%X Abstract: Black pieces always appear on the image margin while we scan the thicker book, because the middle gap of thicker book is hard to planish. The ordinary threshold method can't achieve the perfect effect, and it will affect character recognition. This paper proposes a new binarization method to scanning image. Based on dynamic threshold, texture analysis is used on partitional images, then partitional images are separated into different types, and different types will have different algorithms to cope with. This method avoids influences brought by black pieces and the change of background luminance.
