Color idea and Modeling for special effects, Visualization, and Multimedia Applications bargains with colour imaginative and prescient and visible computing. This e-book presents an summary of the human visible procedure with an emphasis on colour imaginative and prescient and notion. The e-book then is going directly to talk about how human colour imaginative and prescient and conception are utilized in different functions utilizing computer-generated monitors, corresponding to special effects and data and information visualization.
Color thought and Modeling for special effects, Visualization, and Multimedia Applications is acceptable as a secondary textual content for a graduate-level direction on special effects, computing device imaging, or multimedia computing and as a reference for researchers and practitioners constructing special effects and multimedia functions.

Example text

1 summarizes the different categories of color specification systems. In the following, we discuss some of these in more or less detail. Due to our focus on color in computer graphics related applications, we dedicate the majority of Chapter 3 to those systems that have direct applications in computer graphics and related disciplines. Our goal is to order colors in a rational system while providing as close a model as possible to the way humans perceive colors. We examine several color ordering systems.

COLOR ORGANIZATION AND COLOR MODELS In this chapter we discuss color organization and modeling, which is the attempt to provide a way to describe the set and order of colors perceived by an observer, or those a particular device can produce. 1 INTRODUCTION T O COLOR MODELING A color model (also color solid, color space) is a three-dimensional body used to represent some color organization according to a particular choice of three coordinates that describe color. The attempts to organize colors in some order can be traced back to Leonardo da Vinci’s Notebooks around 1500.

4 BASIC VISUAL MECHANISMS The human visual system comprises many different mechanisms. The earliest, and most basic ones involve luminance and contrast perception. 1 Early vision: luminance perception Luminance perception is accomplished by a sensitivity to a broad range of luminance variations. , 14 levels in a logarithmic scale, each level ten times higher than the previous one), from the luminance of a dim star, to that of the bright sunlight. However, at any given moment, the sensitivity is limited to a window of two log-units, matched to the ambient illumination.
