Third International Conference on Image and Graphics (ICIG'04)  
We present a database of full spatial and spectral resolution images of everyday objects captured with a novel multi-spectral device: the Applied Spectral Imaging c Spectracube camera. We summarise the operation of the device and present a study of its spectral accuracy before demonstrating the usefulness of the data set by using it to evaluate different White Point Correction transforms: transforms which map RGBs under one illuminant to a corresponding set of RGBs under a different light. We
