The Deceived Brain: Coding and Illusion
Need help registering?
We perceive the world through the processing of information given by our senses. Sometimes, this processing is faulty, leading to illusions: shapes or sounds that we perceive differently from their physical reality. These illusions have delighted children and scientists alike for centuries.
This lecture reveals how simple geometric illusions can be modelled mathematically, based on our understanding of how visual signals are coded and decoded by the brain, leading to a better understanding of how we process information.
