UniCtrl: Improving the Spatiotemporal Consistency of Text-to-Video Diffusion Models via Training-Free Unified Attention Control

1 code implementation4 Mar 2024 Xuweiyi Chen, Tian Xia, Sihan Xu

Video Diffusion Models have been developed for video generation, usually integrating text and image conditioning to enhance control over the generated content.

Inversion-Free Image Editing with Natural Language

1 code implementation7 Dec 2023 Sihan Xu, Yidong Huang, Jiayi Pan, Ziqiao Ma, Joyce Chai

We show that when the initial sample is known, a special variance schedule reduces the denoising step to the same form as the multi-step consistency sampling.

CycleNet: Rethinking Cycle Consistency in Text-Guided Diffusion for Image Manipulation

1 code implementation NeurIPS 2023 Sihan Xu, Ziqiao Ma, Yidong Huang, Honglak Lee, Joyce Chai

Our empirical studies show that Cyclenet is superior in translation consistency and quality, and can generate high-quality images for out-of-domain distributions with a simple change of the textual prompt.
