Feature-specific interactions in salience from combined feature contrasts: Evidence for a bottom-up saliency map in V1
"... Items that stand out from their surroundings, that is, those that attract attention, are considered to be salient. Salience is generated by input features in many stimulus dimensions, like motion (M), color (C), orientation (O), and others. We focus on bottom-up salience generated by contrast betwe ..."

On the Graded Salience Hypothesis
"... 2003) you o¤er an alternative to the interactionist view that assumes the priority of context and selective compliance with contextual information. Your ‘‘Graded Salience Hypothesis’ ’ (GSH) claims that lexical processing takes priority over contextual processing. In the initial phase of language co ..."

to answer three questions concerning your theory. Giora: At the outset, let me first elaborate a bit on the ‘‘priority’ ’ of sa-lient meanings (Giora 1997, 1999). Following Fodor (1983), the Graded Salience Hypothesis assumes two di¤erent types of mechanisms that run parallel: a modular, bottom-up mechanism
On the connections between saliency and tracking
"... Amodel connecting visual tracking and saliency has recently been proposed. This model is based on the saliency hypothesis for trackingwhich postulates that track-ing is achieved by the top-down tuning, based on target features, of discriminant center-surround saliency mechanisms over time. In this w ..."

Bottom-Up Learning of Phonemes: A Computational Study
"... We present a computational evaluation of a hypothesis according to which distributional information is su-cient to acquire allophonic rules (and hence phonemes) in a bottom-up fashion. The hypothesis was tested using a measure based on information theory that compares distributions. The test was con ..."

HYPOTHESIS Discrimination learning with variable stimulus ‘salience’
"... Background: In nature, sensory stimuli are organized in heterogeneous combinations. Salient items from these combinations ‘stand-out ’ from their surroundings and determine what and how we learn. Yet, the relationship between varying stimulus salience and discrimination learning remains unclear. Pre ..."

Statistical Visual Computing Laboratory,
"... It has been suggested that saliency mechanisms play a role in perceptual organization. This work evaluates the plausibility of a recently proposed generic principle for visual saliency: that all saliency decisions are optimal in a decision-theoretic sense. The discriminant saliency hypothesis is com ..."

is combined with the classical assumption that bottom-up saliency is a center-surround process to derive a (decision-theoretic) optimal saliency architecture. Under this architecture, the saliency of each image location is equated to the discriminant power of a set of features with respect
Some fingerprints of V1 mechanisms in the bottom up saliency for visual selection
"... A unique vertical bar among horizontal bars is salient and pops out perceptually regardless of the observer’s goals. Physiological data have suggested that mechanisms in the primary visual cortex (V1) contribute to the high saliency of such a unique basic feature, but fail to indicate whether V1 pla ..."

like a red-vertical bar among red-horizontal and green-vertical bars is explained, under the hypothesis that the bottom up saliency at any location is signalled by the activity of the most active cell respond-ing to it regardless of the cell’s preferred features such as color and orientation. While
Saliency Detection via Divergence Analysis: A Unified Perspective
"... A number of bottom-up saliency detection algorithms have been proposed in the literature. Since these have been developed from intuition and principles inspired by psychophysical studies of human vision, the theoretical relations among them are unclear. In this paper, we present a unifying perspecti ..."
