A Hierarchical Probabilistic Model for Rapid Object Categorization in Natural Scenes

Figure 6

PDs of selected object structures.

(A), Average posterior probability of being an animal scene based on each selected structure. The thin lines indicate the standard deviation. The insert shows the PD of the posterior probability of being an animal scene based on the structure. (B), The structures with odd indices shown in (A). (C), Relative occurring frequency and entropy of the 70 selected structures. (D)–(F), Same format as (A)–(C) respectively for car structures. (G), Ten examples of fitted generalized Gaussian PDs of the amplitudes of the ICs of joint probability based on the selected animal structures. (H), Examples (10) of fitted generalized Gaussian PDs of the amplitudes of the ICs of joint probability based on the selected car structures.
