Foreground Extraction Based on the Brightness Perception
Foreground extraction is to separate the objects of interest based on the whole image cognition. In this paper, a foreground extraction model based on brightness perception is proposed by combining the visual brightness perception and level set method ...

Brightness/darkness induction and the genesis of a contour
Visual contours often result from the integration or interpolation of fragmented edges.The strength of the completion increases when the edges share the same contrast polarity (CP).

Difference information in brightness perception [PDF]
Contour information generated by moving retinal images has been shown by others to be the principal determinant of perceived color. The data presented here show that, for brightness, this information reflects only differences between adjacent stimulus areas.

Separation of edge detection and brightness perception
When a low spatial frequency noise mask is superimposed onto a luminance staircase, the perceived brightness pattern is dramatically altered although the edges remain visible. We measured contrast thresholds for the edges and for the illusory scalloping (Chevreul-illusion), as a function of noise center spatial frequency.

Research on Street Color Environment Perception Based on CEP-KASS Framework
The color of urban streets plays a crucial role in shaping a city’s image, enhancing street appeal, and optimizing the experience of citizens. Nevertheless, the relationship between street color environment and residents’ perceptions has rarely been ...

Edge integration and the perception of brightness and darkness
How do induced brightness and darkness signals from local and remote surfaces interact to determine the final achromatic color percept of a target surface? An emerging theory of achromatic color perception posits that brightness and darkness percepts are computed by weighting and summing the induction signals generated at edges in a scene.

Sonification supports perception of brightness contrast [PDF]
In complex visual representations, there are several possible challenges for the visual perception that might be eased by adding sound as a second modality (i.e. sonification). It was hypothesized that sonification would support visual perception when facing challenges such as simultaneous brightness contrast or the Mach band phenomena. This hypothesis

Excess Success in “Ray of hope: Hopelessness Increases Preferences for Brighter Lighting”
Dong, Huang, and Zhong (2015) report five successful experiments linking brightness perception with the feeling of hopelessness. They argue that a gloomy future is psychologically represented as darkness, not just metaphorically but as an actual ...

A note concerning the relationship between the Adelson’s Argyle illusion and Cornsweet edges [PDF]
Adelson’s Argyle illusion and the Craik-O’Brien-Cornsweet illusion are two noteworthy brightness illusions. In the Argyle illusion two identical gray areas are perceived to have radically different brightness levels when they are surrounded by a

Consistency of individual differences in brightness perception [PDF]
In previous studies, we have measured individual differences in simultaneous brightness discrimination between a long-duration (500 msec or more) comparison pulse and a set of briefer test pulses of the same luminance. Some observers judge the comparison pulse to be brighter than all test pulses in a range from 20 to 320 msec.
