Abstract

In view of the traditional processing defects of histogram image, this paper proposes a new histogram equalization algorithm about second generation wavelet integer transform. Firstly, the method of three level lifting was used to improve to the wavelet integer transform and to extract the low frequency coefficients. Secondly, the low frequency wavelet coefficients are divided into four sub images with the help of the average luminance wavelet coefficient. Each sub image was extracted by histogram equalization. Finally, the four sub images were merged in order to construct an enhanced image. The experiment results showed that the algorithm of this paper is better in image luminance maintenance and noise controlling and has clearer details. The visual effects of the enhanced images can be applied in remote sensing satellite and the processing of medical images, etc.
