Classifier performance across domains.

Classifiers are trained to distinguish cotton/wool from silk/satin. The first column represents the classifier trained on photographs, and the second column represents the classifier trained on paintings. In the first row, the classifiers are tested on images of the same type they were trained on (i.e., trained and tested on photos, and trained and tested on paintings). In the second row, the classifiers are tested on the other medium, i.e., trained on photos and tested on paintings and vice versa.
