Effects of spatial and temporal context on color categories and color constancy.
Color constancy is the ability to assign a constant color to an object independent of changes in illumination. Color constancy is achieved by taking context information into account. Previous approaches that have used matching paradigms to quantify color constancy found degrees of constancy between 20% and 80%. Here, we studied color constancy in a color-naming task under different conditions o...
متن کاملTemporal asynchrony and spatial perception
Collinear facilitation is an enhancement in the visibility of a target by laterally placed iso-oriented flankers in a collinear (COL) configuration. Iso-oriented flankers placed in a non-collinear configuration (side-by-side, SBS) produce less facilitation. Surprisingly, presentation of both configurations simultaneously (ISO-CROSS) abolishes the facilitation rather than increases it - a phenom...
متن کاملEffects of motion and configural complexity on color transparency perception.
We tested whether motion and configural complexity affect perceived transparency. A series of five coherent chromatic transformations in color space was applied across a figure: translation, convergence, shear, divergence and rotation. The stimuli consisted of a bipartite or a checkerboard configuration (10 x 10 degrees), with a central static or moving overlay (5 x 5 degrees). Three different ...
متن کاملNatural Effect of Spatial and Temporal Color Sequence on Human Color Impression
The degrees of pairs of terms applied to color sequences, such as natural-unnatural, have been investigated previously. Two terms, natural and complex (or unnatural), were described by Ohi & Kawasaki (1996), where after several terms were commonly used to describe the characteristics and associative meanings of colors (Sivik, 1997). In previous studies by this author, the various effects of tem...
متن کاملSmoothness and flicker perception of temporal color transitions
We present results from two experiments designed to explore temporal properties of human color vision relevant to dynamic lighting applications. Sensitivity for smoothness perception of linear temporal transitions and flicker visibility was tested. Stimuli in the first experiment were linear color transitions, varying in either lightness, chroma or hue, around a base color represented in CIE LC...
