Abstract: |
Color constancy is important for various applications where color features are extracted. In general, color constancy is computed based on all image colors. However, not all pixels contain relevant information for color constancy. Eventually, biased pixel values may decrease the performance of such methods. To this end, we propose to use subsets of pixels, containing only relevant information, instead of the entire pixel set for estimating the illuminant. Prior segmentation is performed to learn for different image categories which pixel set is most appropriate for a reliable estimation. Experiments on real-world scenes show that for certain categories, estimations are far more accurate using image parts than when using the entire image. |
