Visual form perception 6041 words
Peter U. Tse and Howard C. Hughes In the absence of any apparent effort, the human visual system recovers the 3 dimensional form of the visible environment from inherently ambiguous 2 dimensional retinal images. How this feat is accomplished is perhaps the most fundamental problem faced by vision science. Despite the impression that vision seems effortless, a vast amount of processing is involv...
متن کاملVisual Perception of Spatial Subjects
Principally, any imaging technology consists of two consecutive, though strictly separated processes: data acquisition and subsequent processing to generate an image that can be looked at, either on a monitor screen or printed on paper. Likewise, the physiological process of viewing can be separated into vision and perception, though these processes are much more overlapping. Understanding the ...
متن کاملPerception and action in 'visual form agnosia'.
A single case study of a patient with 'visual form agnosia' is presented. A severe visual recognition deficit was accompanied by impairments in discriminating shape, reflectance, and orientation, although visual acuity and colour vision, along with tactile recognition and intelligence, were largely preserved. Neuropsychological and behavioural investigations have indicated that the patient is a...

متن کاملFlexibility of spatial averaging in visual perception.
The classical receptive field (RF) concept-the idea that a visual neuron responds to fixed parts and properties of a stimulus-has been challenged by a series of recent physiological results. Here, we extend these findings to human vision, demonstrating that the extent of spatial averaging in contrast perception is also flexible, depending strongly on stimulus contrast and uniformity. At low con...
