Quality Performance of LD, SD and HD Video Encoded with Dirac and H.264/AVC


This paper compares the video quality performance of low definition (LD), standard definition (SD) and high definition (HD) video signals encoded with H.264/AVC and Dirac using full-reference (PSNR and SSIM) and no-reference metrics (JPEG-NR) for different bit rates. It is shown that H.264 outperforms Dirac concerning quality for all resolutions.
