Abstract

In order to objectively predict the quality of gamut mapping images, this paper analyzed the mapping principles of different gamut mapping algorithms and found that there were mainly color and structural distortions in gamut mapping images. Based on this, this paper presented a no-reference quality metric for gamut mapping images based on color and structural distortions. For color distortion, this paper calculated the rate of abnormal hue and the Kullback-Leibler divergence between the statistical distribution of the three components of the image(e. g., R, G, and B) and the ideal uniform distribution. In terms of structural distortion, it extracted the entropy and the fourth-order moments, and extracted statistical features in brightness and saturation components. Subsequently, combined with the subjective scores and extracted features, it used the back propagation neural network(BPNN) to train the quality prediction model. Finally, this paper employed the model to evaluate the quality of gamut mapping images. Extensive experiments conducted on three gamut mapping databases prove the proposed method is superior to the existing quality evaluation models in evaluating the quality of gamut mapping images.
