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

A fast color constancy scheme for automobile video cameras
TL;DR: The proposed CC scheme uses combination of a static method for illuminant estimation called White Patch Retinex (WPR) and a computationally efficient linear transformation model for WB correction of the images to avoid the field flicker noise.

A perceptually optimized JPEG-LS coder for color images
Chun-Hsien Chou,Kuo-Cheng Liu +1 more
TL;DR: In this paper, the JPEG-LS coder in the near-lossless compression mode is perceptually optimized by making coding errors imperceptible or minimally noticeable, and the performance of the perceptually optimize coder is superior to that of the un-optimized coder for achieving the same visual quality.

Development of micromarkers with various photoluminescence colors as tracers for shadowing pursuits.
TL;DR: Micromarkers with five photoluminescence colors were developed as tracers for shadowing pursuits and were non-destructively identified using a microscopic FT-IR spectrometer and a microscopic spectrometers equipped with a fluorescence detector.

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.
