Texfusion: Synthesizing 3d textures with text-guided image diffusion models

T Cao, K Kreis, S Fidler, N Sharp… - Proceedings of the …, 2023 - openaccess.thecvf.com
We present TexFusion (Texture Diffusion), a new method to synthesize textures for given 3D
geometries, using only large-scale text-guided image diffusion models. In contrast to recent …

Differentially private diffusion models

T Dockhorn, T Cao, A Vahdat, K Kreis - arXiv preprint arXiv:2210.09929, 2022 - arxiv.org
While modern machine learning models rely on increasingly large training datasets, data is
often limited in privacy-sensitive domains. Generative models trained with differential privacy …
