The Mathematics of Photography

Featuring Samuli Siltanen

Thursday, September 12
6:30 pm to 7:30 pm ET

(in person)

In our digital era, photos are stored as numbers in smartphones and computers.  Enhancing or filtering pictures just means changing those numbers in a good way.  But how should we process those numbers for the best photos?  With mathematics, of course!  Join Samuli Siltanen, Professor of Industrial Mathematics and Vice Dean of the Faculty of Science at the University of Helsinki, Finland, as he shows us how to brighten photos with the square root, how to reveal original colors from a 1970s snapshot using the logarithm, and how to remove unwanted objects from pictures using smart averaging.

Thursday, September 19, from 6:30 pm to 7:30 pm ET (in person)
Artificial intelligence is breaking new ground every week.  It writes essays, drives cars, and identifies dogs, cats, and bicycles from photos.  Much of this is based on neural networks, which coarsely mimic the brain.  Take a closer look at the computations behind AI in this presentation led by Samuli Siltanen, Professor of Industrial Mathematics and Vice Dean of the Faculty of Science at the University of Helsinki, Finland.  Amazingly, we will see that neural networks use only elementary school math to work their magic, that orienteering strategies have implications on learning, and that the automatic “learning” that AI code does is akin to a mountaineer looking for the lowest valley in thick fog.  Register at momath.org/mathofAI.
