A Hierarchical Probabilistic Model for Rapid Object Categorization in Natural Scenes

Figure 1

Hierarchical probabilistic model of object categorization in natural scenes.

Object category is modeled as a composition of a set of geometrically related parts and each part is represented by a PD of a set of natural object structures. Natural context is modeled by a PD of natural context structures. Object categorization in natural scenes is performed as statistical inference. All the PDs were estimated from natural objects and context.
