Abstract
An integrated method for modeling the handoff between cameras for tracking a specific individual, including: creating a representation of overlaps, gaps, and allowable movement among the fields of view of the cameras, wherein the representation is modeled as states in a Hidden Markov Model (HMM); training the HMM using video of people walking through the fields of view of the cameras; selecting a person to be tracked; and identifying the best camera area using the HMM.
