ABSTRACT:
Human gestures are detected and/or tracked from a pair of digital video images. The pair of images may be used to provide a set of observation vectors that provide a three dimensional position of a subject's upper body. The likelihood of each observation vector representing an upper body component may be determined. Initialization of the model for detecting and tracking gestures may include a set of assumptions regarding the initial position of the subject in a set of foreground observation vectors.
