The Rate-Distortion-Perception Trade-Off with Algorithmic Realism
Yassine Hamdi, Aaron B. Wagner, Deniz Gündüz
Realism constraints (or constraints on perceptual quality) have received considerable recent attention within the context of lossy compression, particularly of images. Theoretical…
Rate-Distortion-Perception Trade-off with Strong Realism Constraints: Role of Side Information and Common Randomness
Yassine Hamdi, Aaron B. Wagner, Deniz Gündüz
In image compression, with recent advances in generative modeling, existence of a trade-off between the rate and perceptual quality has been brought to light, where the perceptual…
The Rate-Distortion-Perception Trade-off: The Role of Private Randomness
Yassine Hamdi, Aaron B. Wagner, Deniz Gündüz
In image compression, with recent advances in generative modeling, the existence of a trade-off between the rate and the perceptual quality (realism) has been brought to light, whe…
Low-Rate, Low-Distortion Compression with Wasserstein Distortion
Yang Qiu, Aaron B. Wagner
Wasserstein distortion is a one-parameter family of distortion measures that was recently proposed to unify fidelity and realism constraints. After establishing continuity results…
Optimal Redundancy in Exact Channel Synthesis
Sharang M. Sriramu, Aaron B. Wagner
We consider the redundancy of the exact channel synthesis problem under an i.i.d. assumption. Existing results provide an upper bound on the unnormalized redundancy that is logarit…
Wasserstein Distortion: Unifying Fidelity and Realism
Yang Qiu, Aaron B. Wagner, Johannes Ballé +1
We introduce a distortion measure for images, Wasserstein distortion, that simultaneously generalizes pixel-level fidelity on the one hand and realism or perceptual quality on the…
