Title:
Computational modelling of visual crowding

Abstract:
To understand how the human brain represents and processes information, the interdisciplinary field of computational neuroscience is becoming increasingly important. In this talk I will first give an introduction to what this field is about and then present some ongoing work on computational modelling of a visual effect called 'crowding'.

Crowding refers to the phenomenon that perception of peripherally viewed shapes is impaired when surrounded by similar shapes, and may be one of the reasons why we for example have to move our eyes when reading. Several models have been proposed to explain how the crowding effect comes about in the brain, but none of them is really satisfactory. The existing models will briefly be reviewed and an alternative model, based on population coding, will be presented.
