TLDR
A survey of color imaging can be found in this article, where the fundamental concepts of color perception and measurement are first presented us-ing vector-space notation and terminology, along with common mathematical models used for representing these devices.Abstract:
This paper surveys current technology and research in the area of digital color imaging. In order to establish the background and lay down terminology, fundamental concepts of color perception and measurement are first presented us-ing vector-space notation and terminology. Present-day color recording and reproduction systems are reviewed along with the common mathematical models used for representing these devices. Algorithms for processing color images for display and communication are surveyed, and a forecast of research trends is attempted. An extensive bibliography is provided.read more

Color asymmetry in 3D imaging: Influence on the viewing experience
TL;DR: An increase in color asymmetry between the viewer's left-eye and right-eye images decreased the image quality evaluation scores, and some content-specific features were less sensitive to changes compared to close-up images with brighter objects and backgrounds.

Rainbow color map distorts and misleads research in hydrology – guidance for better visualizations and science communication
Michael Stoelzle,Lina Stein +1 more
TL;DR: To overcome the use of the rainbow color maps in science, some tools and techniques focusing on improvement of typical visualization types in hydrological science are proposed and guidance on how to avoid, improve and trust color in a proper and scientific way is given.

Colour Correlation-based Matching
Sylvie Chambon,Alain Crouzil +1 more
TL;DR: Nine color spaces and three different methods have been investigated to evaluate their suitability for stereo matching and the results show to what extent stereo matching can be improved with color.

Bag---of---Colors for biomedical document image classification
TL;DR: In this article, the importance of color in addition to the frequently used texture and grey level features was evaluated for biomedical image classification and it was shown that bags-of-colors in combination with the Scale-Invariant Feature Transform (SIFT) provided an image representation allowing to improve the classification quality.

Some methods for classification and analysis of multivariate observations
TL;DR: The k-means algorithm as mentioned in this paper partitions an N-dimensional population into k sets on the basis of a sample, which is a generalization of the ordinary sample mean, and it is shown to give partitions which are reasonably efficient in the sense of within-class variance.

Vector Quantization and Signal Compression
Allen Gersho,Robert M. Gray +1 more
TL;DR: The author explains the design and implementation of the Levinson-Durbin Algorithm, which automates the very labor-intensive and therefore time-heavy and expensive process of designing and implementing a Quantizer.
