Tone and Gamut Mapping for High Dynamic Range and Colour Gamut Imaging: Vision Models, Techniques and Applications

Tone and Gamut Mapping for High Dynamic Range and Colour Gamut Imaging: Vision Models, Techniques and Applications explains tone and color gamut mapping in HDR and WCG imaging within a framework of vision science, presenting the underlying principles and latest practical methods. In addition, it highlights how the use of vision models is a key element of all state-of- the-art methods for these emerging technologies. This book provides university researchers and graduate students in computer science, computer engineering, vision science, and R&D engineers insights into the science and methods of tone and color gamut mapping in HDR and WCG.
