Image Quality Assessment using Foveated Wavelet Error Sensitivity and Isotropic Contrast

In this paper, we propose a new image quality evaluation method, which is based on foveation spatial error sensitivity model and wavelet error sensitivity model. The image quality is measured by isotropic contrast and the standard deviation of the errors of the wavelet coefficients in subbands with the weighting factors that are determined by two models. Experiments on a test database comprising JPEG and JPEG 2000 compressed images have shown that the proposed metric can achieve very good correlation with subjective evaluation.
