Neon Color Spreading: A Review

Perception, 1997
This paper is about a phenomenon that combines a delicate beauty with a profoundsignificance for understanding visual perception. The neon-like glow of a color that escapesthe boundaries of a real figure and fills the surrounding area until it is halted by theboundaries of an illusory figure has an ethereal quality unlike any other brightness and ...

Neon Color Spreading Promoted by Motion Information

Optical Review, 1998
We conducted experiments to investigate the effects of head-motion and object-motion to produce a perception of neon color spreading. Our experimental results indicated that a two-dimensional motion of yellow patches promoted the color spreading. A horizontal head-motion with motion parallax and three-dimensional pictorial depth information together ...

Color spreading algorithm for the retail industry

Computers & Industrial Engineering, 1992
Abstract One of the problems which many companies face is the distribution of inventory from one or more centrally located distribution centers. The retail, industry, and in particular the women's clothing industry, faces the additional problem that not only does the merchandise have to be distributed but it must be distributed in such a way that ...

Amodal Completion as Another Perception of Color-Spreading Stimuli

Perceptual and Motor Skills, 1993
We made a solid three-dimensional object of the Redies-Spillmann figure and found two kinds of completely different phenomena. First, transparent color-spreading was observed in the empty space around the object. Second, another perceptual organization occurred: observers perceived a cross as a cross-shaped slit through which to see, and then they ...

Illusory Color Spread from Apparent Motion

2017
Abstract Color from motion describes the perception of subjective color that spreads over physically achromatic regions that are seen in apparent motion. Multiple frames are shown in quick succession, each frame composed of a random placement of differently colored dots on an achromatic background.

NP-Completeness of Spreading Colored Points

2010
There are n points in the plane and each point is painted by one of m colors where m ≤ n. We want to select m different color points such that (1) the total edge length of resulting minimal spanning tree is as small as possible; or (2) the total edge length of resulting minimal spanning tree is as large as possible; or (3) the perimeter of the convex ...

Layered depth-of-field rendering using color spreading

Proceedings of the 12th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry, 2013
Depth of field (DoF) is a depth range outside of which objects are blurred. DoF has been widely used in photography and films by artists and is expected to be applied to realistic image rendering and virtual reality applications in the area of computer graphics. This paper presents a framework that produces DoF effect with high quality and performance.

Constrained Acquisition of Ink Spreading Curves From Printed Color Images

IEEE Transactions on Image Processing, 2011
Today's spectral reflection prediction models are able to predict the reflection spectra of printed color images with an accuracy as high as the reproduction variability allows. However, to calibrate such models, special uniform calibration patches need to be printed.

Adaptive Spread-Transform Dither Modulation for Color Image Watermarking

IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008
Based on the improved Watson's model, an adaptive spread-transform dither modulation (ASTDM) algorithm is proposed for efficient color image watermarking. The luminance masking threshold is modified to be consistent with amplitude without affecting the original parameters.
