Analysis of colour display characteristics

Predicting colours across multiple display devices requires implementation of device characterization, gamut mapping, and perceptual models. This thesis studies characteristics of CRT, LCD monitors and projectors. It compares existing models and introduces a new model that improves existing calibration algorithms. Gamut mapping assigns a mapping between two different colour spaces. Previously, the focus of gamut mapping has been between monitor and printer, which have relatively different gamut shape. Implementation and result of existing models are compared and a new model is introduced that its output images are as good as the best available models but runs in less time. DLP projectors with a different technology require a more complex calibration algorithm. A new approach for calibrating DLP projectors is introduced with a significantly better performance on predicting RGB data given tristimulus values. At the end, a new calibration method, using Support Vector Regression is introduced.
