Video Quality Metric for Bandwidth Control via Joint SSIM and Bit Rate

摘要：

　　In this paper we present an experiment to assess the wireless video quality in the presence of network bandwidth.On the other side,we give the users perception-understood as both information assimilation and subjective satisfaction-of video quality.The experimental results show that for the purpose of bandwidth control,optimization using the classical SSIM does not match up to that of subjective quality data much.Then we bridge this gap between SSIM and subjective quality data by constructing a new quality metric that accounts for both encoding parameters (bit rate),and network parameter (bandwidth).The average correlation coefficient for three video sequences tested is as high as 0.93 with the proposed metric,in contrast with the SSIMs 0.85
