The time course of figure-ground reversal.
We report the results from five experiments employing a modified version of the short-term visual matching (STVM) method introduced by Driver and Baylis (1996). In STVM, participants see a study display with ambiguous figure-ground relations. After the study display, participants have to decide which of two shapes in a match display was seen before in the study display. STVM has been used by Ve...
متن کاملReal-Time Maintenance of Figure-Ground Segmentation
An approach to figure-ground segmentation based on a 2dimensional histogram in feature space is presented. The histogram is then analyzed with a peak-finding algorithm designed with real-time performance in mind. The most significant peaks in the histogram are backprojected to the image to produce an object mask. The method is applied to segmentation based on a 2-D color space and also on a com...
متن کاملFigure-Ground Segmentation - Pixel-Based
Background subtraction is a widely used concept to detect moving objects in videos taken from a static camera. In the last two decades several algorithms have been developed for background subtraction and were used in various important applications such as visual surveillance, sports video analysis, motion capture, etc.Various statistical approaches have been proposed to model scene background....
متن کاملNoise destroys feedback enhanced figure-ground segmentation but not feedforward figure-ground segmentation
Figure-ground (FG) segmentation is the separation of visual information into background and foreground objects. In the visual cortex, FG responses are observed in the late stimulus response period, when neurons fire in tonic mode, and are accompanied by a switch in cortical state. When such a switch does not occur, FG segmentation fails. Currently, it is not known what happens in the brain on s...
متن کاملRunning the figure to the ground: Figure-ground segmentation during visual search
We examined how figure-ground segmentation occurs across multiple regions of a visual array during a visual search task. Stimuli consisted of arrays of black-and-white figure-ground images in which roughly half of each image depicted a meaningful object, whereas the other half constituted a less meaningful shape. The colours of the meaningful regions of the targets and distractors were either t...
