Natural image statistics mediate brightness ‘ filling in ’ Steven
Although the human visual system can accurately estimate the reflectance (or lightness) of surfaces under enormous variations in illumination, two equiluminant grey regions can be induced to appear quite different simply by placing a light–dark luminance transition between them. This illusion, the Craik–Cornsweet– O’Brien (CCOB) effect, has been taken as evidence for a low-level ‘filling-in’ me...
متن کاملNatural scene statistics mediate the perception of image complexity
Humans are sensitive to complexity and regularity in patterns [YKM13, FK97]. The subjective perception of pattern complexity is correlated to algorithmic (Kolmogorov-Chaitin) complexity as defined in computer science [LV08], but also to the frequency of naturally occurring patterns [HGS10]. However, the possible mediational role of natural frequencies in the perception of algorithmic complexity...
متن کاملTexture brightness filling-in
The masking procedure by Paradiso and Nakayama (1991) (Vision Research, 31, 1221-1236) was used to investigate brightness filling-in within textures made of line elements: a texture stimulus was masked by a second stimulus containing a square contour. When a uniform texture was presented, the texture region inside the masking square appeared darkened and a small number of texture elements were ...
متن کاملSpectral statistics in natural scenes predict hue, saturation, and brightness.
The perceptual color qualities of hue, saturation, and brightness do not correspond in any simple way to the physical characteristics of retinal stimuli, a fact that poses a major obstacle for any explanation of color vision. Here we test the hypothesis that these basic color attributes are determined by the statistical covariations in the spectral stimuli that humans have always experienced in...
