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 …

JND-based Perceptual Rate Distortion Optimization for AV1 Encoder

AV1 is the next-generation open video coding format, and it can achieve significant coding efficiency with novel coding tools. It supports Lagrangian rate distortion optimization (RDO) method to optimize the coding performance. However, the …
