Sample images from the three types of appearance datasets studied in this paper. Left panel: material texture dataset (KTH-TIPS2); Middle panel: animal texture dataset (AniTex); Right panel: vehicle appearance dataset (VehApp). The images range from roughly homogeneous (KTH-TIPS2) to partially homogeneous (AniTex), and to inhomogeneous (VehApp). (Best viewed in color)
