Xiaokang Chen

I am currently a fourth-year Ph.D student at Peking University (PKU), supervised by Professor Gang Zeng. Before that, I received my Bachelor’s degree at Peking University in July 2019.


My research interests are in Computer Vision, including Self-Supervised Learning, 2D/2.5D Semantic Segmentation, Semantic Scene Completion and Object Detection.
