A comparative study of color image compression standards using perceptually driven quality metrics

The task of comparing the performance of different codecs is strictly related to the research in the field of objective quality metrics. Even if several objective quality metrics have been proposed in literature, the lack of standardization in the field of objective quality assessment and the lack of extensive and reliable comparisons of the performance of the different state-of-the-art metrics often make the results obtained using objective metrics not very reliable. In this paper we aim at comparing the performance of three of the existing alternatives for compression of digital pictures, i.e. JPEG, JPEG 2000, and JPEG XR compression, by using different objective Full Reference metrics and considering also perceptual quality metrics which take into account the color information of the data under analysis.
