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

Dichromatic color perception in a two stage model: Testing for cone replacement and cone loss models
TL;DR: A two stage model of dichromatic color perception that consists of a first sensor layer with gain control followed by an opponent encoding transformation and is validated using existing data and by using predictions on known test images for detecting dichromacy.

Design of color screen sets for robustness to color plane misregistration
TL;DR: To quantitatively measure the effect of registration errors, a notion of “visual equivalence” is proposed, and three propositions under which visual equivalence can be achieved, even when registration errors occur are derived.

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.
