This book provides the reader with an understanding of what color is, where color comes from, and how color can be used correctly in many different applications. The authors first treat the physics of light and its interaction with matter at the atomic level, so that the origins of color can be appreciated. The intimate relationship between energy levels, orbital states, and electromagnetic waves helps to explain why diamonds shimmer, rubies are red, and the feathers of the Blue Jay are blue. Then, color theory is explained from its origin to the current state of the art, including image capture and display as well as the practical use of color in disciplines such as computer graphics, computer vision, photography, and film.

Color Imaging: Fundamentals and Applications

High quality video sequences are required for the evaluation of tone mapping operators and high dynamic range (HDR)
displays. We provide scenic and documentary scenes with a dynamic range of up to 18 stops. The scenes are staged
using professional film lighting, make-up and set design to enable the evaluation of image and material appearance. To
address challenges for HDR-displays and temporal tone mapping operators, the sequences include highlights entering
and leaving the image, brightness changing over time, high contrast skin tones, specular highlights and bright, saturated
colors. HDR-capture is carried out using two cameras mounted on a mirror-rig. To achieve a cinematic depth of field,
digital motion picture cameras with Super-35mm size sensors are used. We provide HDR-video sequences to serve as a
common ground for the evaluation of temporal tone mapping operators and HDR-displays. They are available to the
scientific community for further research.

— Local-dimming backlight techniques can significantly improve the static contrast and power consumption of LCD panels. Several local-dimming backlight systems have been previously reported. However, there is currently no comprehensive description regarding the evaluation of such systems. This paper proposes some methods for evaluating the power consumption, brightness, and contrast performance of local-dimming backlight systems and discusses the general artifacts affecting the image quality for these systems.

Evaluation of LCD local-dimming-backlight system

In this letter, a new backlight dimming technique that considers perceptual image quality based on a structural similarity (SSIM) metric is proposed. Conventional algorithms cannot accurately control the optimal trade-off between image quality and power consumption; image quality is therefore degraded in some images. In contrast, the proposed algorithm calculates the allowable target error based on the SSIM metric in real time using the relation function between SSIM and the mean square error (MSE). It can therefore optimally reduce power consumption while preserving the perceptual image quality over the target level. Experimental results show that the proposed algorithm successfully maintains the target SSIM for all test images and sequences. Additionally, the average SSIM of the proposed algorithm is up to 0.034 higher than those of the benchmark algorithms.

SSIM Preservation-Based Backlight Dimming

High Dynamic Range displays offer higher brightness, higher contrast, better color reproduction and lower power consumption compared to conventional displays available today. In addition to these benefits, it is possible to leverage the unique design of HDR displays to overcome many of the calibration and lifetime degradation problems of liquid crystal displays, especially those using light emitting diodes. This paper describes a combination of sensor mechanisms and algorithms that reduce luminance and color variation for both HDR and conventional displays even with the use of highly variable light elements.
