Dengxin Dai


Welcome

I am a Postdoctoral Researcher in the ​​Computer Vision Laboratory at ETH Zurich, working with Prof. Luc Van Gool. Before that, I was a PhD student under the supervision of Prof. Luc Van Gool and Prof. Gerhard Schmitt.

My current research interests lie in (1) Autonomous Driving; 2) Vision Algorithms with Limited/Weak Supervision; and (3) Computational Photography.

Student Projects: I enjoy the chance of supervising motivated students for research projects. If you have interest in working with me, feel free to contact me.
