The perception of form and motion

Current Opinion in Neurobiology, 1993
Although form and motion are two distinct aspects of visual processing, they do not start as separate entities in the visual system. Early analyses extract discontinuities in various image attributes and these can trace the outline of a form. When displaced, the same image features can give rise to impressions of motion. Recent work has overturned many

Visual form perception

Contemporary Physics, 1975
Abstract This article deals with the way in which vertebrate, and in particular primate, visual systems are organized for the detection of spatially distributed light stimuli, i.e. for form perception. The principles of this organization are of concern to physicists who design and employ pattern recognition machines for various purposes, as well as to ...

Attentional Biases in Geometric form Perception

The Quarterly Journal of Experimental Psychology Section A, 2000
This paper reports the operation of robust attentional bias to the top and right during perception of small, single geometric forms. Same/different judgements of successively presented standard and comparison forms are faster when local differences are located at top and right rather than in other regions of the forms. The bias persists when form size

The Perception of Solid Form in Early Infancy

Child Development, 1978
Day and McKenzie determined the rate of habituation of fixation of young infants to repeated visual presentations of a cube. They found the habituation rate to be the same when the stimulus orientation changed between presentations as when it was fixed, and they interpreted this as evidence of shape constancy. However, a failure to discriminate between

Form Perception

1974
Publisher Summary This chapter discusses the form perception in nonhuman primates. The major methodological considerations in studying form perception are in specifying the stimulus and in insuring that the stimulus is appropriate for S. To obtain ecological validity, stimuli used should be representative of the real situations to which one wishes to ...

Body Locus and Form Perception

Perceptual and Motor Skills, 1977
Forms were drawn on the palms, forearms, or biceps of 42 subjects, with vision excluded. Subjects were then required to make a visual match to the drawn forms. It was expected that the accuracy of form recognition would be a direct function of the sensitivity of the receptor surface.

PERCEPTION AND ACTION IN ‘VISUAL FORM AGNOSIA’

Brain, 1991
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.

Visual perception of tree forms

Building and Environment, 2006
Abstract This study, made in the cities of Adapazari, Duzce, and Bolu, has three fundamental goals. The first one is the evaluation of visual quality and strength of each tree form, second is the determination of visual quality and strength of different tree forms next to each other, and the third goal of this study is determining the effects of ...

Cortical dynamics of form perception [PDF]

Proceedings of the International Joint Conference on Neural Networks, 2003., 2004
The neocortex is the seat of all higher biological intelligence. All sensory and cognitive neocortex is organized into layered circuits. A recent family or LAMINART models proposes how these layered circuit embody bottom-up, top-down, and horizontal interactions within the visual cortex to generate percepts of visual form.
