Scalable object recognition architecture

A method ( 500 ) of processing received objects in a rendering system ( 230 ) is disclosed. The rendering system ( 230 ) has a plurality of detection schemes ( 234 - 1 through 234 -N), with each detection scheme ( 234 - 1 through 234 -N) having an associated object group type. The method ( 500 ) determines ( 516 ) whether a detection scheme ( 234 ) which already has grouped objects exists. If such a detection scheme ( 234 ) does not exist and a previously received object has been stored, then the method ( 500 ) determines ( 536 ) in descending priority order whether one of the detection schemes ( 234 ) is operative to group the received object with the previously received object. If it is determined ( 526 ) that none of the detection schemes is operative to group the received object with the previously received object, then the previously received object is output ( 528 ) for rendering and the received object is stored ( 528 ). If it is determined ( 536 ) that one of the detection schemes is operative to group the received object with the previously received object, then the received object is grouped with the previously received object.
