Visual object representation is the process of encoding object information in visual cortex for purposes of object identification, discrimination, evaluation, and memory storage.
Characteristics
Computational difficulty.
Object vision is so computationally difficult that even the best computer vision systems achieve only rudimentary performance compared to humans. The difficulty lies in the enormous complexity and variability of visual object information. The representation of an object on a retina or camera is an isomorphic pattern of response rates or pixel values. This pattern is extremely complex (on the order of a million pixel-like signals for human vision) and hopelessly variable – the same object can produce a virtual infinity of retinal images depending on its position, orientation, lighting, partial occlusion, and plastic deformation. Object information at this level is...
