Constructive Approaches to Perception-Aware Lossy Source Coding: Information-Theoretic Guidelines

Ali Hussein, Jun Chen, Chao Tian +1

Perception-aware lossy source coding has attracted significant recent interest. It augments the classical distortion criterion with an explicit perception constraint, thereby enabl…

Source-Channel Separation Theorems for Distortion Perception Coding

Chao Tian, Jun Chen, Krishna Narayanan

It is well known that separation between lossy source coding and channel coding is asymptotically optimal under classical additive distortion measures. Recently, coding under a new…

Rate-Distortion-Perception Tradeoff Based on the Conditional-Distribution Perception Measure

Sadaf Salehkalaibar, Jun Chen, Ashish Khisti +1

This paper studies the rate-distortion-perception (RDP) tradeoff for a memoryless source model in the asymptotic limit of large block-lengths. The perception measure is based on a…

Rate-Distortion-Perception Tradeoff for Gaussian Vector Sources

Jingjing Qian, Sadaf Salehkalaibar, Jun Chen +5

This paper studies the rate-distortion-perception (RDP) tradeoff for a Gaussian vector source coding problem where the goal is to compress the multi-component source subject to dis…

On Self-Adaptive Perception Loss Function for Sequential Lossy Compression

Sadaf Salehkalaibar, Buu Phan, Likun Cai +4

We consider causal, low-latency, sequential lossy compression, with mean squared-error (MSE) as the distortion loss, and a perception loss function (PLF) to enhance the realism of…
