About me
Dr. Lei Sun
My research interests include multi-modal fusion, image restoration, event-based algorithms, image/video generative models, and semantic segmentation.
I am interested in event cameras, a neuromorphic sensor that imitates the behavior of the human eye. Check out the introduction of the event camera and one of my project pages.
I am also doing research on multi-modal fusion and image/video generative models.
Before joining INSAIT, I led projects aimed at improving smartphone camera image processing pipelines in collaboration with several smartphone camera brands.
