A New Reduced-Reference Image Quality Assessment Method Based on SSIM

Because human visual perception is highly adapted for extracting structural information from a scene, but the existing SSIM index is a full reference method which needs entire information of reference images. In this paper, we develop a reduced reference SSIM method and evaluate its performance through a set of assessment criteria, as well as comparison to both EPSNR and SSIM methods on a database of images compressed with JPEG and JPEG2000.
