Description: Histogram equalization can effectively enhance the digital image processing, its main drawback is the treatment of significant loss of gray-scale digital image level, and strengthen weak. Proposed overlap in the sub-block histogram equalization, based on the introduction of gray-scale histogram equalization reserves management approach, making the processed image contrast is greatly enhanced, without loss of gray-scale, and the adjacent pixels transition level grayscale, image soft and true. Dealing with the serious effects of the image block, based on human visual characteristics and the characteristics of digital image data, the percentage of the ranks of proposed adaptive method to effectively reduce blocking artifacts.
