Video transmission over Internet is often afflicted by various packet losses. The packet-lever forward error correction (FEC) is often used for error recovery in order to enhance the end-to-end video quality. However, the quality metrics used in traditional FEC scheme designing such as peak signal-to-noise ratio (PSNR) have been founded not correlate well with human perceptual quality and usually...
