In video coding, understanding the real bitrate requirements that correspond to the desired quality is a key feature. It’s possible to assess quality by using appropriate objective metrics such as PSNR and SSIM Index, or simply through subjective methods as the Mean Opinion Score (MOS). Objective metrics are good if the aim is evaluating video… Continue reading H.264 output quality and bitrate
With this post I begin a series of articles covering the issue of image and video quality assessment through both objective and subjective methods. Where possible, I will also attach a little piece of Matlab code in order to show a possible implementation of the suggested algorithms.
