Jelena Kovacevic, Martin Vetterli, Laurent Lorenzo Balmelli Quadranti: Efficient processing of quadtree data. Lucent Technologies, Henry T Brendzel, February 25, 2003: US06526176 (8 worldwide citation)

Processing of quadtree data structures is significantly improved with the use of an indexing that is arranged to insure that the index value of a node in column/row i and column/row j differs from the index value of a node in column/row k and row/column i by a value that is constant. With such an in ...
