Nominator's project description

The perception of material properties has only recently emerged as a major topic in vision science. Remarkably, human observers are capable of inferring complex physical properties of objects, such as gloss or roughness, from a brief glimpse at a surface. How this is achieved in our brains is still a mystery, but it is becoming increasingly clear that in many cases visual correlates of these properties are used as rough estimates of complex physical processes. In this project, Dr. Doerschner will investigate the neural basis of material perception. In previous work, she used advanced computer graphics and behavioral techniques to study reflectance perception in complex 3D scenes. More recently, she has used fMRI to investigate brain mechanisms of perception. This places her in the unique position to bring together computational and neural methods to investigate what information the visual system extracts from the inherently ambiguous retinal signal, and how this information is processed in the brain to yield vivid impressions of material qualities.
