Iβm a PhD candidate from Insight Lab, National Key Laboratory for Multimedia Information Processing, School of Computer Science, Peking University, supervised by Prof. Lei Ma and Prof. Tiejun Huang. I received my B.S. degree from Beihang University in 2023.
My research interest includes computer vision and computer graphics, especially in the fields of 3D vision and spike vision.
