On the Robustness of Color Texture Descriptors across Illuminants

In this paper we evaluate several extensions of Local Binary Patterns to color images. In particular, we investigate their robustness with respect to changes in the illuminant color temperature. To do so, we recovered the spectral reflectances of 1360 texture images from the Outex 13 data set. Then, we rendered the images as if they were taken under 33 different illuminants. For each combination of a training and test illuminant, we measured the classification performance of the texture features considered. The results of this extensive experimentation are reported and critically discussed.
