A V1 Model of Pop Out and Asymmetty in Visual Search
نویسنده
چکیده
Visual search is the task of nding a target in an image against a background of distractors. Unique features of targets enable them to pop out against the background, while targets deened by lacks of features or conjunctions of features are more diicult to spot. It is known that the ease of target detection can change when the roles of gure and ground are switched. The mechanisms underlying the ease of pop out and asymmetry in visual search have been elusive. This paper shows that a model of segmentation in V1 based on intracortical interactions can explain many of the qualitative aspects of visual search.

Orientation pop-out processing in human visual cortex
Visual stimuli can "pop out" if they are different to their background. There has been considerable debate as to the role of primary visual cortex (V1) versus higher visual areas (esp. V4) in pop-out processing. Here we parametrically modulated the relative orientation of stimuli and their backgrounds to investigate the neural correlates of pop-out in visual cortex while subjects were performin...
متن کاملHow selective are V1 cells for pop-out stimuli?
Many neurons in visual area V1 respond better to a pop-out stimulus, such as a single vertical bar among many horizontal bars, than to a homogeneous stimulus, such as a stimulus with all vertical bars. Many studies have suggested such cells represent neural correlates of pop-out, or more generally figure-ground segregation. However, preference for pop-out stimuli over homogeneous stimuli could ...

متن کاملContextual influences in V1 as a basis for pop out and asymmetry in visual search.
I use a model to show how simple, bottom-up, neural mechanisms in primary visual cortex can qualitatively explain the preattentive component of complex psychophysical phenomena of visual search for a target among distracters. Depending on the image features, the speed of search ranges from fast, when a target pops-out or is instantaneously detectable, to very slow, and it can be asymmetric with...
متن کاملPsychophysical Tests of the Hypothesis of a Bottom-Up Saliency Map in Primary Visual Cortex
A unique vertical bar among horizontal bars is salient and pops out perceptually. Physiological data have suggested that mechanisms in the primary visual cortex (V1) contribute to the high saliency of such a unique basic feature, but indicated little regarding whether V1 plays an essential or peripheral role in input-driven or bottom-up saliency. Meanwhile, a biologically based V1 model has sug...
