Abstract:
In this paper, a quadrant structure for two- dimensional objects is described.The concept
of quadrant order is presented. A direct procedure for encoding higher order quadrant
is discussed. Operators associated with quadrants are provided, namely, the subsume relation,
,the intersect operator, ∩, and the # -product,#. Union, intersection, and complement
of quadrants encoded objects are computed. Finally, the implementation of quadrant operators
on general purpose computer as well as data structures for a quadrant are developed.
