1. A method for identifying and tracking an object from two-dimensional data pictorially representing said object, comprising the steps of: receiving at least one set of said two-dimensional data pictorially representing said object, wherein said at least one set corresponds to one temporal instance and said two-dimensional data is generated by a sensor; and processing said at least one set of said two-dimensional data using at least one tracker-identifier for providing an output signal containing a) a type of said object, b) a position or an orientation of said object in three-dimensions and c) an articulation or a shape change of said object in said three dimensions, wherein said type of the object is determined using a spatial model description of said object.
