Exploring outdoor appearance changes with transient scene attributes

The appearance of outdoor scenes changes dramatically with lighting and weather conditions, time of day, and season. We relate visual changes to scene attributes, which are human-nameable concepts used for high-level description of scenes. They carry semantic meaning and are more flexible than a categorical representation of scenes. While the discriminative scene attributes proposed in [Patterson and Hays 2012] distinguish scenes from each other, we focus on transient attributes which describe changes in appearance within each scene under real-world conditions.
