1. A process to identify a person in image data comprising:
- executing a training phase, the training phase comprising;
using one or more body part detectors to learn one or more body parts;
generating classifiers for the one or more body parts;
determining a spatial distribution among the one or more of the body parts; and
determining a set of probabilities, the set of probabilities relating to one or more of a probable location and scale of the person in the image data given that a particular body part detector has fired, a probability that there is a person in the image data given that a particular body part detector has fired, and a probability that a particular body part detector can fire at a particular location and a particular scale; and
executing a detection phase, the detection phase comprising;
applying the one or more body part detectors to an image;
combining output of the one or more body part detectors; and
determining a maximum of the combination of output of the one or more body part detectors.

Abstract
A process identifies a person in image data. The process first executes a training phase, and thereafter a detection phase. The training phase learns body parts using body part detectors, generates classifiers, and determines a spatial distribution and a set of probabilities. The execution phase applies the body part detector to an image, combines output of several body part detectors, and determines maxima of the combination of the output.
