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 …

Avs Encoding Optimization with Perceptual Just Noticeable Distortion Model

Integrating efficient visual perceptual cues into standardized video coding framework can improve performance significantly. In this paper we propose to enhance AVS encoder by using the latest just noticeable distortion (JND) model to adjust DCT …
