Jiwen Yu

I will be enrolling the Department of Electrical and Electronic Engineering at the University of Hong Kong as a PhD student in 2024 fall, supervised by Prof. Xihui Liu at HKU-MMLab. I will be working on research topics related to Computer Vision and Embodied AI. Prior to this, I obtained my master's degree from Peking University, where I was advised by Prof. Jian Zhang.

AnimateZero: Video Diffusion Models are Zero-Shot Image Animators
Jiwen Yu, Xiaodong Cun, Chenyang Qi, Yong Zhang, Xintao Wang, Ying Shan, Jian Zhang
ArXiv, 2023
code / arXiv / paper / project page

We propose AnimateZero, a zero-shot approach for image animation on generated images. AnimateZero also supports various applications, such as video editing, frame interpolation, real image animation, and more.

CRoSS: Diffusion Model Makes Controllable, Robust and Secure Image Steganography

NeurIPS, 2023
code / arXiv

We propose a novel diffusion-based image steganography framework named Controllable, Robust, and Secure Image Steganography (CRoSS). This framework offers significant advantages in controllability, robustness, and security compared to cover-based image steganography methods. Importantly, these benefits are achieved without requiring additional training.

FreeDoM is a simple but effective training-free method generating results under control from various conditions using unconditional diffusion models.

Zero-Shot Image Restoration Using Denoising Diffusion Null-Space Model
Yinhuai Wang*, Jiwen Yu*, Jian Zhang (*denotes equal contribution)
ICLR, 2023   (Oral Presentation)
project page / arXiv / code

We bring Range-Null space Decomposition (RND) into diffusion models, enabling diverse image restoration tasks in a zero-shot manner, without extra training or optimization.
