1. A method for detecting one or more targets, comprising: acquiring one or more depth images from one or more depth sensing image sensors, a first depth image of the one or more depth images includes a plurality of pixels; generating a classification map associated with the first depth image, the step of generating includes assigning to one or more pixels of the plurality of pixels a probability that the one or more pixels is associated with a particular target of the one or more targets, the one or more targets include a first target representing at least a portion of a first body part and a second target representing at least a portion of a first prop; fitting at least one computer model of one or more computer models onto at least a portion of the classification map, the one or more computer models include at least a first model of the first target and at least a second model of the second target; performing skeletal tracking on the first target; performing prop tracking on the second target; and reporting a first position of the first target and a second position of the second target.
