Cues and strategies for color constancy: perceptual scission, image junctions and transformational color matching
The identification of objects, illuminants, and transparencies are probably the most important perceptual functions of color. This paper examines the effects of perceptual scission, image junctions, color adaptation, and color correlations on identification. Simulations of natural illuminants, materials, and filters were used in a forced-choice procedure to simultaneously measure thresholds for...
متن کاملAccuracy of color scission for spectral transparencies.
When surfaces are overlaid by a transparent filter, color scission refers to the perceptual separation of the colors of the image into the colors of the underlying surface and the color of the overlaying layer. We used filter matching to measure the accuracy of color scission for simulated physical filters and materials. Standard filters were placed on various sets of chromatic materials and ma...
متن کاملTransparent layer constancy under changes in illumination color: Does task matter?
If the perceived transmittances of transparent objects are matched across illuminants, only incomplete constancy is found. This implies that physically identical objects may appear different. Nevertheless, it was reported in the literature that subjects could almost perfectly identify such objects across illuminants, even if a transparency impression was suppressed by violating geometric transp...
متن کاملColor strategies for object identification
We measured accuracy of object identification across illuminations on the basis of color cues. Four similarly shaped real objects, three of the same reflectance, were separated into pairs under distinct colored real lights. Observers were asked to pick the odd object. Correct and incorrect identifications formed systematic patterns that could not be explained by color-constancy, contrast-consta...
متن کاملColor constancy by combining low-mid-high level image cues
In general, computational methods to estimate the color of the light source are based on single, low-level image cues such as pixel values and edges. Only a few methods are proposed exploiting multiple cues for color constancy by incorporating pixel values, edge information and higher-order image statistics. However, expanding color constancy beyond these low-level image statistics (pixels, edg...
