An extended image database for colour constancy

Abstract

We present an extended version of an image database presented in 2003, to test colour constancy and other kinds of visual and image processing algorithms. Big technology improvements have been done in the last eleven years, however the motivations to present this upgrade are not only technological. We decided to address other characteristics related to vision, like e.g. high dynamic range. Moreover, to address computer vision related problems (e.g. illuminant or reflectance estimation) we have made available a set of data regarding objects, backgrounds and illuminants used.
