Features Accurate annotation – Average key point number for each object is more than 100. (see counts histogram on website) Multiple annotation methods – Labelmap, sketch, hierarchical decomposition, geometry information
Examples: Airplane (Frontal-side view) Lotus Hill Transportation 9 Subset content ContentHierarchical decomposition of close-up objects Number of images Publicly accessible 209 Internal testing 4558 Object category airplane, bicycle, bus, car, tractor, truck, sailboat, helicopter, motorcycle Multiple views Objects are groups into multiple views.
