Calculate correlated color temperature from CIE uv coordinates correlatedColorTemperature = cct(uvArray) The CIE has defined methods for estimating the relationship between chromaticity coordinates (uv) and the color temperature of a blackbody radiator. This routine accepts 1960 UCS chromaticity coordinates, uv, and returns the color temperature in degrees Kelvin of the correlated blackbody radiators. This value is often used to summarize the properties of a light source. This routine requires the information in the file: cct.mat Reference: Wyszecki & Stiles pgs. 227-228 correlatedColorTemperature UV : [u1,u2,u3 ...; v1, v2, v3 ...] chromaticity coordinates as a column vector. Example: colorTemp = cct([.31,.32]') Copyright ImagEval Consultants, LLC, 2003.
