This paper describes two classical image quality assessment methods: PSNR (Peak Signal to Noise Ratio) and SSIM (Structural Similarity), both of which will be used to evaluate the lossy transmis-sion image quality. Experimental results show that the SSIM method is superior to PSNR method when packet error rate is higher than 0.25 for low-motion videos, while the PSNR method is better than SSIM method for high-motion videos.</span>
