Adaptation and visual salience.
We examined how the salience of color is affected by adaptation to different color distributions. Observers searched for a color target on a dense background of distractors varying along different directions in color space. Prior adaptation to the backgrounds enhanced search on the same background while adaptation to orthogonal background directions slowed detection. Advantages of adaptation we...
متن کاملSalience of visual parts.
Many objects have component parts, and these parts often differ in their visual salience. In this paper we present a theory of part salience. The theory builds on the minima rule for defining part boundaries. According to this rule, human vision defines part boundaries at negative minima of curvature on silhouettes, and along negative minima of the principal curvatures on surfaces. We propose t...
متن کاملVisual Salience of Algebraic Transformations
Information processing researchers have assumed that algebra symbol skills depend on mastery of the abstract rules presented in the curriculum (Matz, 1980; Sleeman, 1986). Thus, students’ ubiquitous algebra errors have been taken as indicating the need to embed algebra in rich contextual settings (Kaput, 1995; National Council of Teachers of Mathematics [NCTM], Algebra Working Group, 1998). Thi...
متن کاملDeep Salience: Visual Salience Modeling via Deep Belief Propagation
Visual salience is an intriguing phenomenon observed in biological neural systems. Numerous attempts have been made to model visual salience mathematically using various feature contrasts, either locally or globally. However, these algorithmic models tend to ignore the problem’s biological solutions, in which visual salience appears to arise during the propagation of visual stimuli along the...
متن کاملVisual Salience-Guided Mesh Decomposition
Generally, decomposition is a leverage to obtain the componential representation from a whole. After the decomposition step is executed, the decomposed components can be individually selected, grouped, and analyzed based on the properties of interest. According to Hoffman and Singh’s theory [1], there are at least three factors that determine the salience of a part: the protrusion, the boundary...
