Invertible Diffusion Models for Compressed Sensing

no code implementations25 Mar 2024 Bin Chen, Zhenyu Zhang, Weiqi Li, Chen Zhao, Jiwen Yu, Shijie Zhao, Jie Chen, Jian Zhang

To enable such memory-intensive end-to-end finetuning, we propose a novel two-level invertible design to transform both (1) the multi-step sampling process and (2) the noise estimation U-Net in each step into invertible networks.

AnimateZero: Video Diffusion Models are Zero-Shot Image Animators

1 code implementation6 Dec 2023 Jiwen Yu, Xiaodong Cun, Chenyang Qi, Yong Zhang, Xintao Wang, Ying Shan, Jian Zhang

For appearance control, we borrow intermediate latents and their features from the text-to-image (T2I) generation for ensuring the generated first frame is equal to the given generated image.

DiffLLE: Diffusion-guided Domain Calibration for Unsupervised Low-light Image Enhancement

no code implementations18 Aug 2023 Shuzhou Yang, Xuanyu Zhang, Yinhuai Wang, Jiwen Yu, YuHan Wang, Jian Zhang

Specifically, we adopt a naive unsupervised enhancement algorithm to realize preliminary restoration and design two zero-shot plug-and-play modules based on diffusion model to improve generalization and effectiveness.

Unlimited-Size Diffusion Restoration

1 code implementation1 Mar 2023 Yinhuai Wang, Jiwen Yu, Runyi Yu, Jian Zhang

Our simple, parameter-free approaches can be used not only for image restoration but also for image generation of unlimited sizes, with the potential to be a general tool for diffusion models.
