Auto-Regressive Image Synthesis with Integrated Quantization

ECCV 2022poster

"Deep generative models have achieved conspicuous progress in realistic image synthesis with multifarious conditional inputs, while generating diverse yet high-fidelity images remains a grand challenge in conditional image generation. This paper presents a versatile framework for conditional image g…

Marginal Contrastive Correspondence for Guided Image Generation

CVPR 2022oral

Exemplar-based image translation establishes dense correspondences between a conditional input and an exemplar (from two different domains) for leveraging detailed exemplar styles to achieve realistic image translation. Existing work builds the cross-domain correspondences implicitly by minimizing f…

EMLight: Lighting Estimation via Spherical Distribution Approximation

AAAI 2021technical

Illumination estimation from a single image is critical in 3D rendering and it has been investigated extensively in the computer vision and computer graphic research community. On the other hand, existing works estimate illumination by either regressing light parameters or generating illumination ma…

Sparse Needlets for Lighting Estimation With Spherical Transport Loss

ICCV 2021poster

Accurate lighting estimation is challenging yet critical to many computer vision and computer graphics tasks such as high-dynamic-range (HDR) relighting. Existing approaches model lighting in either frequency domain or spatial domain which is insufficient to represent the complex lighting conditions…

Unbalanced Feature Transport for Exemplar-Based Image Translation

CVPR 2021poster

Despite the great success of GANs in images translation with different conditioned inputs such as semantic segmentation and edge map, generating high-fidelity images with reference styles from exemplars remains a grand challenge in conditional image-to-image translation. This paper presents a genera…
