Ph.D. Student @ Zhejiang University

I am a third-year Ph.D. student at Zhejiang University in Hangzhou, China, advised by Prof. Yi Yang. My research interests include 3D Computer Vision, controllable image generation, digital human reconstruction & generation, and embodied intelligence. Prior to that, I obtained my B.Sc. in Artificial Intelligence from Zhejiang University in 2023 (Outstanding Graduate, ranked 2nd in major). I was also a member of the Mixed Class at Chu Kochen Honors College (CKC) of Zhejiang University.

TransNormal

TransNormal: Dense Visual Semantics for Diffusion-based Transparent Object Normal Estimation

Mingwei Li, Hehe Fan, Yi Yang

arXiv 2026

We leverage dense visual semantics to guide diffusion-based single-step normal prediction with wavelet regularization for transparent object normal estimation.

BideDPO

BideDPO: Conditional Image Generation with Simultaneous Text and Condition Alignment

Dewei Zhou, Mingwei Li, Zongxin Yang, Yu Lu, Yunqiu Xu, Zhizhong Wang, Zeyi Huang, Yi Yang

ICLR 2026

We propose a bidirectionally decoupled DPO method to resolve text-condition conflicts in controllable text-to-image generation, significantly improving both text and condition adherence.
