I am a forth-year Ph.D. candidate of Computer Science and Technology at School of Electron and Computer Engineering, Peking University, advised by Prof. Li Yuan. Before this, I got a B.E. degree of computer science at College of Computer Science, Sichuan University.

My recent research interests includes 3D content and video generation.

A Simple Visual-Textual Baseline for Pedestrian Attribute Recognition

Xinhua Cheng*, Mengxi Jia*, Qian Wang, Jian Zhang

IEEE Transactions on Circuits and Systems for Video Technology (TCSVT), 2022

Paper Code

We model pedestrian attribute recognition as a multimodal problem and build a simple visual-textual baseline to captures the intra- and cross-modal correlations.
