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 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, the performing skeletal tracking includes receiving position information regarding the second target, the position information is taken into consideration when determining the first position of the first target.
