Abstract :
In this paper three image quality metrics are compared: mean-square error (MSE), noise quality measure (NQM), and structural information metric (SIM). Such a comparison is made in order to evaluate the performance of those different metrics under practical conditions. Experimental results along with statistical indices of performance are provided. The referred results suggest that there are situations in which the MSE-based metric outperforms the two other considered metrics.
