Purdue Engineering Distinguished Lecture Series: "The Moon Camera"

William T. Freeman, Professor of Electrical Engineering and Computer Science (EECS) at Massachusetts Institute of Technology, gave this virtual lecture on January 26, 2022, followed by a panel discussion. 

The goal is to take a picture of the Earth from space, using ground-based observations of the Moon. Freeman described the project, why it's hard, and why it would be useful to do. Freeman described different approaches (exploiting diffuse reflections, cast shadows, and sunlight phasor fields) and computational imaging spin-offs that have resulted from those approaches, and finished with a current promising approach.
