Visual magic : changing an object just by watching

- Visual illusion reveals neural codes for objects in the brain -

Abstract

We introduce a novel visual illusion in which prolonged viewing of an object alters the apparent shape and material of the subsequently viewed object. Analyses of this ‘Object Aftereffect’ support the idea that the human brain can recognize a complex 3D object from a collection of simple image features, without reconstructing geometrical 3D structure of the object. This finding makes it easier to understand neural codes for objects in the brain, and enables us to control visual appearance of objects by manipulating image features. It will also be useful for improving the current object recognition algorithms to a more human-centered method.
