Object Recognition: Visual Crowding from a Distance
Immediately before a large eye movement, a target object is crowded by clutter near the target's future location. This new finding, from a recent study, shows that the brain's remapping for the anticipated eye movement unavoidably combines features from the target's current and future retinal locations into one perceptual object.
متن کاملCrowding: a cortical constraint on object recognition.
The external world is mapped retinotopically onto the primary visual cortex (V1). We show here that objects in the world, unless they are very dissimilar, can be recognized only if they are sufficiently separated in visual cortex: specifically, in V1, at least 6mm apart in the radial direction (increasing eccentricity) or 1mm apart in the circumferential direction (equal eccentricity). Objects ...
متن کاملCrowding, grouping, and object recognition: A matter of appearance.
In crowding, the perception of a target strongly deteriorates when neighboring elements are presented. Crowding is usually assumed to have the following characteristics. (a) Crowding is determined only by nearby elements within a restricted region around the target (Bouma's law). (b) Increasing the number of flankers can only deteriorate performance. (c) Target-flanker interference is feature-s...
متن کاملCrowding—An essential bottleneck for object recognition: A mini-review
Crowding, generally defined as the deleterious influence of nearby contours on visual discrimination, is ubiquitous in spatial vision. Crowding impairs the ability to recognize objects in clutter. It has been extensively studied over the last 80 years or so, and much of the renewed interest is the hope that studying crowding may lead to a better understanding of the processes involved in object...
