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

Temporal full-colour tuning through non-steady-state upconversion
TL;DR: This work demonstrates a convenient, versatile approach to dynamically fine-tuning emission in the full colour range from a new class of core-shell upconversion nanocrystals by adjusting the pulse width of infrared laser beams and suggests that the unprecedented colour tunability from these nanocry crystals is governed by a non-steady-state upconverting process.

Adaptive homogeneity-directed demosaicing algorithm
Keigo Hirakawa,T.W. Parks +1 more
TL;DR: The proposed demosaicing algorithm estimates missing pixels by interpolating in the direction with fewer color artifacts, and the aliasing problem is addressed by applying filterbank techniques to 2-D directional interpolation.

A novel approach for coding color quantized images
Andre Zaccarin,B. Liu +1 more
TL;DR: An approach to the lossy compression of color images with limited palette that does not require color quantization of the decoded image is presented, which significantly reduces the decoder computational complexity.

Principled halftoning based on human vision models
TL;DR: It is found that the principled approach can lead to a range of useful halftoning algorithms, as the authors trade off speed for quality by varying the complexity of the quality measure and the thoroughness of the search.
