Color spaces and color contrast

The Visual Computer, 1985
With the introduction of low-cost color graphics systems comes a host of problems specifically concerned with the color aspect of the system. This paper discusses two of these problems: the selection and manipulation of colors by (possibly) inexperienced users, and the automatic selection of colors by the system to achieve high contrast effects on the ...

Clustering color segmentation in multi-color space

Proceedings of the 2018 2nd International Conference on Video and Image Processing, 2018
The quality of image segmentation seriously affects the results of digital images analysis and calculation. Aiming at the problem that the parameters of classification and initial center need to be entered for color image segmentation by using k-means clustering algorithm, a k-means clustering algorithm based on multiple color space is proposed for ...

Simple and Efficient Colorization in YCbCr Color Space

18th International Conference on Pattern Recognition (ICPR'06), 2006
We have already proposed a colorization method in RGB color space, where the colorization problem is formulated as the maximum a posteriori (MAP) estimation of a color image given a monochrome image. Markov random field (MRF) is used for modeling a color image which is utilized as a prior for the MAP estimation.

Spectral spaces and color spaces

Color Research & Application, 2003
AbstractIt has long been known that color experiences under controlled conditions may be ordered into a color space based on three primary attributes. It is also known that the color of an object depends on its spectral reflectance function, among other factors.

Color Interpolation for Non-Euclidean Color Spaces

2018 IEEE Scientific Visualization Conference (SciVis), 2018
Color interpolation is critical to many applications across a variety of domains, like color mapping or image processing. Due to the characteristics of the human visual system, color spaces whose distance measure is designed to mimic perceptual color differences tend to be non-Euclidean.

Color pixels classification in an hybrid color space

Proceedings 1998 International Conference on Image Processing. ICIP98 (Cat. No.98CB36269), 2002
We describe a new approach for color image segmentation which is considered as a problem of pixels classification. The algorithm is applied to classify pixels of soccer color images in order to recognize the team of players. The color pixels classification algorithm is achieved in a new color space, the hybrid color space, which is determined thanks to

Filtering color images in the xyY color space

Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101), 2002
This paper presents a new approach to color filtering which operates on the representation of an image in the xyY color space. The filtering scheme, aided by the color mixing rule which applies to the 2D chromatic subspace spanned by the x and y coordinates, is shown to preserve the convexity of the chromatic information.

Skin color detecting unite YCgCb color space with YCgCr color space

2009 International Conference on Image Analysis and Signal Processing, 2009
In order to detect more reliably skin color for color facial image with complicated background, we have presented a detection method based on uniting YCgCb color space with YCgCr color spaced. There exist many colors in nature that are similar to skin color, such as sand, sand beach, soil, stone, cement road, wood, and so on. The things mentioned above
