HEVC VMAF-oriented Perceptual Rate Distortion Optimization using CNN

Video coding standards like HEVC and VVC have achieved significant coding performance. However, the RDO module in coding framework ignores the characteristics of human visual system (HVS), which leads to insufficiency for perceptual video coding. …

VMAF Oriented Perceptual Coding Based on Piecewise Metric Coupling

It has been recognized that videos have to be encoded in a rate-distortion optimized manner for high coding performance. Therefore, operational coding methods have been developed for conventional distortion metrics such as Sum of Squared Error (SSE). …

A VMAF Directed Perceptual Rate Distortion Optimization for Video Coding

Video Multimethod Assessment Fusion (VMAF), as a state-of-the-art learning-based objective assessment metric, has been demonstrated to achieve a stronger correlation with human visual system than others. However, combining multiple metrics by Support …

VMAF Oriented Perceptual Optimization for Video Coding

In the light of low costs and automatic assessment, objective visual quality metrics enjoy many important applications such as perceptual coding. Recently multiple metrics obtain further improvement by means of machine learning. However, due to the …
