The present invention is embodied in a system and method for digitally tracking objects in real time. The present invention visually tracks three-dimensional (3-D) objects in dense disparity maps in real time. Tracking of the human body is achieved by digitally segmenting and modeling different body parts using statistical models defined by multiple size parameters, position and orientation. In addition, the present invention is embodied in a system and method for recognizing mutual occlusions of body parts and filling in data for the occluded parts while tracking a human body. The body parts are preferably tracked from frame to frame in image sequences as an articulated structure in which the body parts are connected at the joints instead of as individual objects moving and changing shape and orientation freely.
A method for tracking an object having plural parts, wherein the object is tracked as an articulated structure, the method comprising:
A method for tracking a human body having multiple body parts comprising:
An object tracking system for dynamically tracking articulated structures within a sequence of images, wherein the structures are made of segmented parts, comprising:
