A New Generic Colour Full Reference Metric

Color image quality depends on many factors, such as the initial capture system and its colour image processing, compression, restoration, transmission, the output device, media and associated viewing conditions. In this paper, we propose a new efficient full reference image quality assessment metric, which is based on human visual system proprieties in order to get the best correspondence with human judgments. The suggested full reference metric is generic (independent of image distortion type). It can be used in different application such as: compression, restoration, etc. The experimental results consider essentially JPEG2000 compressed images and ACE restored image correlate highly with the Mean Opinion Score (MOS). The correlation of the subjective ratings and objective scores illustrate the performance of the proposed metric.
