Abstract: The feature extraction of image prediction technology is a hot and difficult problem in the image processing field.This paper proposed a image difference prediction algorithm containing the fusion image normalization characteristic.Color difference measurement method based on image feature makes full use of the color information of image,and the color information is converted to a color space.And then the image is normalized to a range of specific perspective to extract the image difference feature (IDF) information.Finally,this paper did a lot of experiments,and the experimental results show that the proposed method greatly improves difference prediction performance of color image.At the same time,we preformed the multi-scale analysis for brightness distortion caused by gamut mapping.The results show that the image differential feature based on brightness extracted from different scale images has higher correlation between scale than the general image distortion.
