The microgenesis of the watercolor effect [PDF]
Frontiers in Psychology, 2013 The ‘watercolor effect’ is the wash of illusory color that fills in between two enclosing bichromatic contours. We studied the microgenesis of this illusion by varying the duration of the eliciting stimulus (a yellow/purple contour outlining the ...

Quantifying the Watercolor Effect: from stimulus properties to neural models. [PDF]
Frontiers in Human Neuroscience, 2014 Visual illusions are perceptions that violate our expectations with respect to what we understand about the physical stimulus, for example, surfaces of identical spectral composition that appear to be of different colors. Such phenomena are thought to reveal mechanisms, biases, priors or strategies that the brain uses to interpret the visual ...

Spatial dependence of color assimilation by the watercolor effect. [PDF]
Perception, 2006 Color assimilation with bichromatic contours was quantified for spatial extents ranging from von Bezold-type color assimilation to the watercolor effect. The magnitude and direction of assimilative hue change was measured as a function of the width of a rectangular stimulus. Assimilation was quantified by hue cancellation.

The watercolor effect: quantitative evidence for luminance-dependent mechanisms of long-range color assimilation. [PDF]
Vision Res, 2005 When a dark chromatic contour delineating a figure is flanked on the inside by a brighter chromatic contour, the brighter color will spread into the entire enclosed area. This is known as the watercolor effect (WCE). Here we quantified the effect of color spreading using both color-matching and hue-cancellation tasks.

An improved image processing algorithm for visual characteristics in graphic design [PDF]
PeerJ Computer Science, 2023 Drawing the clothing plan is an essential part of the clothing industry. However, the irregular shape of clothing, strong deformability and sensitivity to light make the fast and accurate realization of clothing image retrieval a very challenging problem.

Asymmetric effects of luminance and chrominance in the watercolor illusion [PDF]
Frontiers in Human Neuroscience, 2014 When bounded by a line of sufficient contrast, the desaturated hue of a colored line will spread over an enclosed area, an effect known as the watercolor illusion. The contrast of the two lines can be in luminance, chromaticity, or a combination of both.

Achromatic watercolor effect: About requirement of formation of sumi painting effect
The Japanese journal of psychology, 2008 The watercolor effect (Pinna, Brelstaff, & Spillmann, 2001) is a new color spreading phenomenon. Pinna et al. (2001) proposed that the watercolor effect is a new Gestalt factor because it determines figure-ground organization more strongly than classical Gestalt factors. We used achroriatic watercolor patterns and varied the lightness of the background

The effect of contrast intensity and polarity in achromatic watercolor effect
Journal of Vision, 2010 The watercolor effect (WCE) is a filling-in phenomenon in a region demarcated by two thin abutting lines. The perceived chromaticity of the region is similar to that of the interior line. We develop a series of achromatic WCE stimuli to induce lightness changes analogous to the induced chromaticity in the chromatic version of the WCE.

Smartphone Based Retouching Method for Watercolor Painting Effect Using Mean Shift Segmentation [PDF]
The Journal of the Korean Institute of Information and Communication Engineering, 2010 We propose a retouching method that converts a photography taken by smartphone to a watercolor painting image using bilateral filtering and mean shift segmentation which are mostly used in image processing. The first step is to convert an input image to fit the screen resolution of smartphone. And next step is to weaken high frequency components of the

Effects of background and contour luminance on the hue and brightness of the Watercolor effect [PDF]
Vision Research, 2017 AbstractConjoint measurement was used to investigate the joint influences of the luminance of the background and the inner contour on hue- and brightness filling-in for a stimulus configuration generating a water-color effect (WCE), i.e., a wiggly bi-chromatic contour enclosing a region with the lower luminance component on the exterior.
