Base Claim:
1. A method for recognizing faces of persons, comprising: training a system to recognize a facial component; populating a first knowledge base with facial components and, for each facial component, the facial component's body part classification, wherein the facial components in the first knowledge base include a first set of facial components extracted from facial identification training image data of a face of a first person at a first set of viewpoints; determining a first set of body part classifications associated with the first set of facial components; for each body part classification in the first set of body part classifications: determining, from the first set of facial components, a subset of facial components that are associated with the body part classification, wherein the facial components in the subset represent a same body part classification of a same person at multiple viewpoints; and determining a probability that a person class of the subset of facial components is the first person; and determining a first body part classification in the first set of body part classifications that maximizes the probability.

Claim 6:
6. The method of claim 1 , wherein determining the probability that the person class of the subset of facial components is the first person comprises: determining a first conditional probability, that a class is the first person, of a facial component of the subset of facial components at a first viewpoint; determining a first posterior probability, that a class is the first person, by multiplying the conditional probability at the first viewpoint by a prior probability, that a class is the first person; determining a second conditional probability, that a class is the first person, of a facial component of the subset of facial components at an additional viewpoint; and determining a second posterior probability, that a class is the first person, by multiplying the second conditional probability by the first posterior probability.
