Recovery of a crowded object by masking the flankers: determining the locus of feature integration.
Object recognition is a central function of the visual system. As a first step, the features of an object are registered; these independently encoded features are then bound together to form a single representation. Here we investigate the locus of this "feature integration" by examining crowding, a striking breakdown of this process. Crowding, an inability to identify a peripheral target surro...
متن کاملCrowding by Invisible Flankers
BACKGROUND Human object recognition degrades sharply as the target object moves from central vision into peripheral vision. In particular, one's ability to recognize a peripheral target is severely impaired by the presence of flanking objects, a phenomenon known as visual crowding. Recent studies on how visual awareness of flanker existence influences crowding had shown mixed results. More impo...
متن کاملCrowding Changes Appearance
Crowding is the breakdown in object recognition that occurs in cluttered visual environments and the fundamental limit on peripheral vision, affecting identification within many visual modalities and across large spatial regions. Though frequently characterized as a disruptive process through which object representations are suppressed or lost altogether, we demonstrate that crowding systematic...
متن کاملThe Neural Correlates of Crowding-Induced Changes in Appearance
Object recognition in the peripheral visual field is limited by crowding: the disruptive influence of nearby clutter. Despite its severity, little is known about the cortical locus of crowding. Here, we examined the neural correlates of crowding by combining event-related fMRI adaptation with a change-detection paradigm. Crowding can change the appearance of objects, such that items become perc...
متن کاملAn Intelligent Paradigm for Multi-Objects Tracking in Crowded Environment
In this paper, we describe a novel object tracking technique in color video sequences, with application to multi-object tracking in crowded scenes. The proposed paradigm integrates object detection into the object tracking process and provide a robust tracking framework under ambiguity conditions. In order to reduce the computational complexity and to increase the robustness, we use a tri-secti...
