I propose that pre-attentive computational mechanisms in primary visual cortex create a saliency map. This map awards higher responses to more salient image locations; these responses are those of conventional V1 cells tuned to input features, such as orientation and color. Hence no separate feature maps, or any subsequent combination of them, is needed to create a saliency map. I use a model to show that this saliency map accounts for the way that the relative difficulties of visual search… Expand
The primary visual cortex creates a bottom-up saliency map
TLDR
This proposal links physiology with psychophysics, thereby making testable predictions some of which are subsequently conrmed experimentally and accounted for behavioral data such as how task diculties can be inuenced by image features and their spatial congurations. Expand
The Primary Visual Cortex Creates a Bottom-up Saliency Map
TLDR
It has been proposed that the primary visual cortex (V1) creates a saliency map using autonomous intra-cortical mechanisms, and the model accounted for behavioral data such as how task difficulties can be influenced by image features and their spatial configurations. Expand
A bottom up visual saliency map in the primary visual cortex, theory and its experimental tests
TLDR
The theoretical proposal that the primary visual cortex (V1) creates a saliency map of the visual space, such that the receptive field location of the most responsive V1 neuron to a scene is most likely selected for attentional processing is presented. Expand
Testing the hypothesis that V 1 creates a bottom-up saliency map
Saliency is the ability of an image location to attract attention or detailed processing. A unique vertical bar among horizontal bars is said to be salient and pops out perceptually. PhysiologicalExpand
Saliency, attention, and visual search: an information theoretic approach.
TLDR
It is demonstrated that a variety of visual search behaviors appear as emergent properties of the model and therefore basic principles of coding and information transmission are demonstrated. Expand
Perceptual learning of pop-out and the primary visual cortex
Abstract I propose that perceptual learning of tasks to detect targets among uniform background items involves changing intra-cortical interactions in the primary visual cortex (V1). This is the caseExpand

TLDR
This work studies the feature integration problem and proposes two improved strategies: first, a weighted linear combination of features using the constraint linear regression algorithm, and second, an AdaBoost based algorithm to approach the feature selection, thresholding, weight assignment, and nonlinear integration in a single principled framework. Expand
Neural Mechanisms of Saliency, Attention, and Orienting
TLDR
Evidence for mechanisms in the primate brain that integrate bottom-up saliency with internal goals for flexible orienting towards behaviorally relevant stimuli is reviewed and novel issues and insights are raised that challenge current views about the neural basis of saliency, attention, and orienting.

Stimulus Saliency Modulates Pre-Attentive Processing Speed in Human Visual Cortex
TLDR
By linking the Posterior Contralateral Negativity (PCN) component to reaction time (RT) performance, this work tested one specific prediction of such salience summation models: expedited shifts of focal-attention to targets with low, as compared to high, target-distracter similarity. Expand
Superior colliculus neurons encode a visual saliency map during free viewing of natural dynamic video
TLDR
A strong test of the saliency hypothesis is conducted by comparing the output of a well-established computational saliency model with the activation of neurons in the primate superior colliculus (SC), a midbrain structure associated with attention and gaze, while monkeys watched video of natural scenes.

We have proposed that a saliency map is an outcome of pre-attentive computation by the primary visual cortex (V1). This awards higher responses, or saliencies, to boundaries between homogeneous inputExpand
Extraction of perceptually salient contours by striate cortical networks
TLDR
The model proposes that intrinsic properties of synchronization account for the increased salience of smooth, closed contours and accounts for a range of reported psychophysical and physiological effects of contour salience. Expand

TLDR
It is proposed that contextual influences serve pre-attentive visual segmentation by causing relatively higher neural responses to important or conspicuous image locations, making them more salient for perceptual pop-out. Expand
Shifts in selective visual attention: towards the underlying neural circuitry.
TLDR
This study addresses the question of how simple networks of neuron-like elements can account for a variety of phenomena associated with this shift of selective visual attention and suggests a possible role for the extensive back-projection from the visual cortex to the LGN. Expand
Computational modelling of visual attention
TLDR
Five important trends have emerged from recent work on computational models of focal visual attention that emphasize the bottom-up, image-based control of attentional deployment, providing a framework for a computational and neurobiological understanding of visual attention. Expand

TLDR
A model used 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 suggests that contextual influences in V1 play a significant role. Expand
Influence of scene-based properties on visual search.

This work has shown that visual search also has access to another level of representation, one that describes properties in the corresponding three-dimensional scene that are three dimensionality and the direction of lighting, but not viewing direction. Expand

TLDR
It is proposed that contextual influences are used for pre-attentive visual segmentation, and this model is the first that performs texture or region segmentation in exactly the same neural circuit that solves the dual problem of the enhancement of contours. Expand

A new hypothesis about the role of focused attention is proposed, which offers a new set of criteria for distinguishing separable from integral features and a new rationale for predicting which tasks will show attention limits and which will not. Expand
