Mohamed Sayed

Hello! I'm Mohamed, a Research Scientist at Niantic, Inc.

I am excited about 3D reconstruction and real-world robust interactive vision systems. My recent projects include depth estimation and reconstruction (SimpleRecon, DoubleTake), soft occlusions for AR effects, and primitive geometry estimation for scenes. I also designed and built the majority of LookOut, an interactive filming-copilot system for automatically pointing a camera during filming.
