Abstract
Peak signal-to-noise ratio (PSNR) is commonly used as a measure for the quality of the reconstructed picture where the original picture is used as reference data. Since the original picture is not available in the video decoder, the receiver cannot evaluate the quality of the reconstructed image from the viewpoint of PSNR. Proposed is an efficient method to estimate PSNR using the statistical distribution of the integer transform coefficient in an H.264 decoder.
