Objective Measurement of Video Quality, PSNR, Color Images, Optimal Weight, DMOS.
In this paper, we propose to use a weighted PSNR for
objective measurement of video quality. Typical videos
consist of three colors: red, blue, and green. Traditionally,
the PSNR of the three colors are computed with equal
weight and used as a measurement of video quality.
Recently, an optimization procedure that finds the
optimal weight vector for a number of parameters has
been proposed. In this paper, we propose to use the
optimization procedure to find the optimal weight vector
for the three colors to obtain a better objective
measurement of video quality. Experimental results
show that the proposed method provides improved
performance over the conventional PSNR method.
