| Abstract(in English) | Classification of scene illumination, rather than estimation of the full spectral power distribution of the illumination, is appropriate and useful for many imaging application. We analyze illuminant classification algorithms designed to group scene illuminant by color temperature. A version of the correlation method suggested by Finlayson et al. is used. Using calibrated images with known illuminants, we propose the improved correlation method by using a scaled version of the red and blue sensor responses. The algorithm is more sensitive to differences in illuminant color temperature. The proposed method is applied to an image database of real scene. Moreover we show that once the illuminant color temperature is estimated, it is possible to predict the camera sensor responses for the same objects viewed under a different illuminant color temperature. |
