Color stereoscopic images requiring only one color image
Optical Engineering, 2007Utilizing remote color stereoscopic scenes typically requires the acquisition, transmission, and processing of two color images. However, the amount of information transmitted and processed is large, compared to either monocular images or monochrome stereo images. Existing approaches to this challenge focus on compression and optimization.

Digital color imaging with color constancy
Systems and Computers in Japan, 2002Abstract“Color constancy” which gives almost constant color perception of an object under illumination of various colors, is an important characteristic in identifying objects by our color vision. This paper proposes an algorithm to add color constancy to a digital camera, which reconstructs an image under arbitrary light conditions by using a pair of ...

Color image resolution conversion
IEEE Transactions on Image Processing, 2005In this paper, we look at the problem of spatially scaling color images. We focus on an approach that takes advantage of the human visual system's color spatial frequency sensitivity. The algorithm performs an efficient least-squares (LS) resolution conversion for the luminance channel and a low-complexity pixel replication/reduction in the chrominance

Color lines: image specific color representation.
Proceedings of the 2004 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2004. CVPR 2004., 2004The problem of deciding whether two pixels in an image have the same real world color is a fundamental problem in computer vision. Many color spaces are used in different applications for discriminating color from intensity to create an informative representation of color.

Color emotions for multi‐colored images
Color Research & Application, 2011AbstractWe investigate the emotional response to colors in ordinary multicolored images. In psychophysical experiments, using both category scaling and interval scaling, observers are asked to judge images using three emotion factors: activity, weight, and heat.

Perceptual and Motor Skills, 1977
There is renewed interest by psychologists in mental imagery. While practical uses of imagery are being rapidly developed, there still remains a great deal to learn about imaging itself. One aspect of imaging is color. A review of the literature provided no research data as to which colors were easiest or hardest to image.

Guided-colorization-based color image coding
2016 Picture Coding Symposium (PCS), 2016This paper proposes guided-colorization-based image coding that utilizes a guide image for encoding chroma components. Up to now, several colorization-based image coding techniques have been proposed. In those techniques, the luma component is encoded by a standard encoder, while the two chroma components by colorization.

Color classification of natural color images
Color Research & Application, 1992AbstractThe present article describes a color classification method that partitions a color image into a set of uniform color regions. The input image data are first mapped from device coordinates into the CIE L*a*b* color space, an approximately uniform perceptual color space.
