A human observer is able to recognize the color of objectsirrespective of the light used to illuminate them. This is calledcolor constancy. A digital camera uses a sensor to measure thereflected light, meaning that the measured color at each pixelvaries according to the color of the illuminant. Therefore, theresulting colors may not be the same as the colors that wereperceived by the observer. Obtaining color constant descriptorsfrom image pixels is not only important for digital photography,but also valuable for computer vision, color-based automatic objectrecognition, and color image processing in general.
This book provides a comprehensive introduction to the field ofcolor constancy, describing all the major color constancyalgorithms, as well as presenting cutting edge research in the areaof color image processing. Beginning with an in-depth look at thehuman visual system, Ebner goes on to:
* examine the theory of color image formation, color reproductionand different color spaces;
* discuss algorithms for color constancy under both uniform andnon-uniform illuminants;
* describe methods for shadow removal and shadow attenuation indigital images;
* evaluate the various algorithms for object recognition andcolor constancy and compare this to data obtained from experimentalpsychology;
* set out the different algorithms as pseudo code in an appendixat the end of the book.
Color Constancy is an ideal reference for practisingengineers, computer scientists and researchers working in the areaof digital color image processing. It may also be useful forbiologists or scientists in general who are interested incomputational theories of the visual brain and bio-inspiredengineering systems.
