A New Moment Based Image Quality Metric
Leida Li, Hancheng Zhu, Deqiang Cheng, Jeng‐Shyang Pan · 2013
This paper presents a new full-reference image quality measure using discrete orthogonal moments. The sign of the moment is considered and the relative difference of the moments is obtained by comparing the absolute moment difference (AMD) with the magnitude of the original moment. A new quality function is proposed, which is an exponential function of the relative moment difference (RMD). Simulation results show the efficiency of the method.
