Sinopsis

The growing importance of colour science in manufacturing industry has resulted in the availability of many excellent textbooks: existing texts or review papers describe the history and development of the Commission Internationale de l’Eclairage (CIE) system (Wyszecki and Stiles, 1982; Hunt, 1998), the prediction of colour difference (McDonald, 1997a; Berns, 2000; Luo, 2002a) and colour appearance (Fairchild, 1998), the relationship of the CIE system to the human visual system (Wandell, 1995; Kaiser and Boynton, 1996), and applications of colour science in technology (Green and MacDonald, 2002). However, the field of colour science is becoming ever more technical and although practitioners need to understand the theory and practice of colour science they also need guidance on how to actually compute the various metrics, indices and coordinates that are useful to the practising colour scientist. The purpose of this book is to describe methods and algorithms for actually computing colorimetric parameters and for carrying out applications such as device characterization, transformations between colour spaces and computation of various indices such as colour differences. A reasonable understanding of the main principles of the CIE system is therefore assumed, although a revision aid is provided in Section 1.3 in the form of a brief review of the CIE system of colorimetry. The reader who wishes to explore the theoretical and historical backgrounds of the topics covered by this book is encouraged to review the alternative texts mentioned above and referred to within this text. We anticipate that computer programmers, colour-image engineers and students of colour science will find this book and the associated MATLAB code useful, but hope that anyone with an interest in colour science will find the book enjoyable and informative.
