I am a senior researcher at OMRON SINIC X Corporation in Tokyo. I am interested in geometric and photometric 3D vision and physics-informed machine learning.
Call for interns: I am looking for an intern who can intensively work with me on a computer vision research problem using deep learning, aiming at publishing a paper at CVPR/ICCV/ECCV/ICML/NIPS.
