Abijith J. Kamath

Research Focus

I want to challenge the frontiers of computational imaging.

I work in the intersection of sampling theory, inverse problems and machine learning for event-driven imaging — with high speed and dynamic range!

Previously at National Institute of Technology Karnataka.
