Unpaired Joint Distribution Modeling via Multi-Scale Image Representations
Yihang Zou, Hui Zhang, Zuowei Shen +1
This paper studies the problem of learning a joint distribution from marginal observations, which is inherently ill-posed due to the ambiguity of feasible couplings. We propose LUD…

Enhancing Low-resolution Image Representation Through Normalizing Flows
Chenglong Bao, Tongyao Pang, Zuowei Shen +2
Low-resolution image representation can be regarded as a special form of sparse representation that retains only low-frequency information while discarding high-frequency component…
