Summary
I am a PhD student in the Communications and Signal Processing (CSP) group at Imperial College London, under the supervision of Prof. Pier Luigi Dragotti. I received a M.Sc. (2020) and B.Sc (2017) degree in Instrumentation Science and Technology from the Beihang University (Beijing, China). My research interests include event-based vision, model-based deep learning, SNNs and remote sensing image processing.
News
We have posted another paper about events-to-video reconstruction: "Enhanced Event-Based Video Reconstruction with Motion Compensation", arxiv preprint:2403.11961. Related code is coming soon!
Projects
