A Hierarchical Probabilistic Model for Rapid Object Categorization in Natural Scenes
Figure 2
Coarse models of geometry of animals (medium-body animals) and cars in natural scenes.
(A), Any animal in natural scenes was modeled by two ellipses, one for the head and one for the body. Any car in natural scenes was modeled by one ellipse. (B), Size (left) and orientation (right) distributions of animal heads in natural scenes. (C), Size (left) and orientation (right) distributions of animal bodies in natural scenes. (D), Size (left) and orientation (right) distributions of cars in natural scenes.
