Guest Gordon Wetzstein is an expert in using math to improve photographs. Such methods have exploded in recent years and have wide-ranging impacts from improving your family photos, to making self-driving cars safer, to building ever-more-powerful microscopes. Somewhere in between hardware and software, he says, is the field of computational imaging, which makes cameras do some pretty amazing things. Wetzstein and host Russ Altman bring it all into focus on this episode of Stanford Engineering’s The Future of Everything podcast.
