An Evaluation of the Next-Generation Image Coding Standard AVIF

摘要

This paper presents a comparative performance evaluation of the newly proposed AV1 Image File Format (AVIF) vs. other state-of-the art image codecs, for natural, synthetic and gaming images. The codecs are compared in terms of Rate-quality curves and BD-Rate savings considering different quality metrics. AVIF results in the best overall performance considering both 4:2:0 and 4:4:4 chroma sub-sampling encoded images.
