ThemeStation: Generating Theme-Aware 3D Assets from Few Exemplars

no code implementations22 Mar 2024 Zhenwei Wang, Tengfei Wang, Gerhard Hancke, Ziwei Liu, Rynson W. H. Lau

To this end, we design a two-stage framework that draws a concept image first, followed by a reference-informed 3D modeling stage.

ComboVerse: Compositional 3D Assets Creation Using Spatially-Aware Diffusion Guidance

no code implementations19 Mar 2024 Yongwei Chen, Tengfei Wang, Tong Wu, Xingang Pan, Kui Jia, Ziwei Liu

Though promising results have been achieved in single object generation, these methods often struggle to model complex 3D assets that inherently contain multiple objects.

3D GAN Inversion with Facial Symmetry Prior

no code implementations CVPR 2023 Fei Yin, Yong Zhang, Xuan Wang, Tengfei Wang, Xiaoyu Li, Yuan Gong, Yanbo Fan, Xiaodong Cun, Ying Shan, Cengiz Oztireli, Yujiu Yang

It is natural to associate 3D GANs with GAN inversion methods to project a real image into the generator's latent space, allowing free-view consistent synthesis and editing, referred as 3D GAN inversion.

Bootstrap Motion Forecasting With Self-Consistent Constraints

no code implementations ICCV 2023 Maosheng Ye, Jiamiao Xu, Xunnong Xu, Tengfei Wang, Tongyi Cao, Qifeng Chen

Also, to model the multi-modality in motion forecasting, we design a novel self-ensembling scheme to obtain accurate teacher targets to enforce the self-constraints with multi-modality supervision.
