Book Description:
A human observer is able to recognize the color of objects irrespective of the light used to illuminate them. This is called color constancy. A digital camera uses a sensor to measure the reflected light, meaning that the measured color at each pixel varies according to the color of the illuminant. Therefore, the resulting colors may not be the same as the colors that were perceived by the observer. Obtaining color constant descriptors from image pixels is not only important for digital photography, but also valuable for computer vision, colorbased automatic object recognition, and color image processing in general. This book provides a comprehensive introduction to the field of color constancy, describing all the major color constancy algorithms, as well as presenting cutting edge research in the area of color image processing. Beginning with an indepth look at the human visual system, Ebner goes on to: examine the theory of color image formation, color reproduction and different color spaces; discuss algorithms for color constancy under both uniform and nonuniform illuminants; describe methods for shadow removal and shadow attenuation in digital images; evaluate the various algorithms for object recognition and color constancy and compare this to data obtained from experimental psychology; set out the different algorithms as pseudo code in an appendix at the end of the book. Color Constancy is an ideal reference for practising engineers, computer scientists and researchers working in the area of digital color image processing. It may also be useful for biologists or scientists in general who are interested in computational theories of the visual brain and bioinspired engineering systems.

Provides direct access to the skills, insights and techniques of some of the postproduction industry's most prominent digital video colorists, delivering practical skills to the postproduction pro seeking to improve their color grading craft. The author interviews and observes 8 professional colorists as they grade a series of real world video images, describing the methods and techniques each artist uses to reach their finalized image. These video images are included on a DVD that allows you to work lockstep with each artist as they grade their images.Though some tools provided may differ from one product to the next, the basic process of video color correction (grading) remains the same. Application agnostic and sure to inspire, The Art of Digital ...
A Comprehensive Guide for Graphic Designers
Color Management shows how to implement color as a practical form of problem solving. It is a consolidated resource, arming designers with an understanding of how to communicate with and manage color in all its aspects and applications: subtractive and additive; pigment, CMYK and RGB; 2-D and 3-D; still and motion. Sensitivity of pigments to light and air and the stability of inks is also detailed, as is the human factor, through issues of color legibility and the physical and psychological effects of color. There are step-by-step systems for achieving accurate color and successful process builds for prepress operations, color sinking, and overprinting, while technical issues of color-printing order, color mixing, dot gain, and color removal are also...
