neighborhood information within each scale and re-
gion hierarchical information between the scales, us-
ing global image features as well as local ones for ob-
servations in the model. This model only exploits up
to second-order cliques, which makes learning and in-
ference much easier. This model combines different
views on the data by layer-specific potentials and the
hierarchical structure accounting for longer range de-
pendencies.
