Data for Colour Research

Kobus Barnard, Lindsay Martin, Brian Funt, and Adam Coath, "A Data Set for Color Research," Color Research and Application, Vol. 27, No. 3, pp. 148-152, 2002. [ Full text (pdf) ]


We present an extensive data set for color research which has been made available on-line (http://www.cs.sfu.ca/~colour/data). The data is especially germane to research into computational color constancy, but we have aimed to make the data as general as possible, and we anticipate a wide range of benefit to research into computational color science and computer vision. Since data is only useful in context, we provide the details of the collection process, including the camera characterization, and the data used to determine that characterization. The most significant part of the data is 743 images of scenes taken under a carefully chosen set of 11 different illuminants. The data set also has several standardized sets of spectra for synthetic data experiments, including some data for fluorescent surfaces.

Keywords: color, colour, colour constancy, image data, illuminant spectra, reflectance spectra, fluorescent spectra
