Fig15. Plot of MSE vs. Bitrate for different codecs for news_qcif video Fig16. Plot of MSE vs. Bitrate for different codecs for foreman_qcif video Fig17. Plot of SSIM vs. Bitrate for different codecs for news_qcif video sequence Fig18. Plot of SSIM vs. Bitrate for different codecs for foreman_qcif video sequence Fig19. Plot of time taken by each codec at QP=30 and QF=10 CONCLUSIONS In this project, a comparative evaluation of H.264, Dirac and AVS part 2 has been performed. Different test sequences have been used in the implementation of these standards and the values obtained are tabulated. In order to evaluate and to decide which video coding standard provides better performance, different metrics such as PSNR, MSE and SSIM are used. For a codec to provide a better performance, it is desired to have a higher PSNR, SSIM and lower MSE with the increase in bitrate. The plots and tabulations show that with the increase in bitrate, there is an increase in PSNR and SSIM and reduction in the MSE in all the standards. Particularly, H.264 performs better when compared to AVS part 2 and Dirac at higher bitrate. This is evident from different plots and tabulations
