Switching template fitting methods during articulated object tracking
Martin Tosas · 2005
This paper describes two methods of fitting deformable templates when tracking articulated objects using particle filters. One method fits a template to each of the links of an articulated object in a hierarchical way. The method first fits a template for the base of the articulated object and then fits a template for each of the links deeper in the hierarchy. The second method fits the whole articulated object as a rigid object, and then refines the fitting for each of the links of the articulated object in a hierarchical way, starting from the base. Advantages and disadvantages of each method are discussed and a way of combining the best of each method in a single tracker is presented.
