Chum, Negative evidences and co-occurences in image retrieval: The benefit of PCA and whitening, in: Proceedings of European Conference on Computer ... Nettetwhitening and coloring operations are used to manipulate the image appearance [19,28]. This is because the appear-ance of an individual image is well encoded in the covari-ance matrix of its features. We call whitening of an indi-vidual image as instance whitening (IW). In this work, we make the first attempt to apply IW in high-level vision tasks
