🧍‍♂️About-me

My name is Jinfu Liu. I am currently an algorithm engineer in DJI. My work focuses on developing On-device AI Technologies and deploying them across DJI’s product lines, such as the Drone series and the OSMO series. Before that, I received my M.S. degree in Sun Yat-sen University (supervised by Prof.Mengyuan Liu), where my research areas are primarily focused on Video Understanding. I received my B.S. degree in Automation from Wuhan University of Technology. During my studies, I was also an intern in Tencent AMS, MeiTuan, and Tencent AI Lab, where my research areas included content understanding, video generation, and digital human generation. Now my research interests are primarily focused on Video Understanding, On-device AI Technologies, and Content Generation. I was also a reviewer in the aforementioned fields (e.g. in the IEEE-TPAMI, ACM-MM, IEEE-ICME, and IEEE-TCSVT).
