A Synonymous Variational Perspective on the Rate-Distortion-Perception Tradeoff

Zijian Liang, Kai Niu, Changshuo Wang +2

The fundamental limit of natural signal compression has traditionally been characterized by classical rate-distortion (RD) theory through the tradeoff between coding rate and recon…

A Theoretical Framework for Rate-Distortion Limits in Learned Image Compression

Changshuo Wang, Zijian Liang, Kai Niu +1

We present a novel systematic theoretical framework to analyze the rate-distortion (R-D) limits of learned image compression. While recent neural codecs have achieved remarkable em…
