The Evaluation System of the Image Quality with Subjective and Objective Uniformity

Abstract

Abstract. Image quality evaluation standard mainly relied on the traditional standard like peak signal to noise ratio (PSNR), but PSNR does not meet people's subjective assessment. To obtain more accurate evaluation with subjective and objective uniformity, the multi-indexes are considered. Our evaluation system includes three parts: (1) grade evaluation; (2) auxiliary evaluation; (3) reference evaluation. The value of grade evaluation is mainly determined by the grade evaluation, and minor modifications are made by the auxiliary evaluation. The reference evaluation provides the traditional objective standards so as to comparative analysis. The results of actual operation show that it is comprehensive and effective.
