| Abstract: | This paper advances and analyzes a series of algorithms for set operations of 2DRE Quadtrees, which changes complicated image operations with high complexity of time and space into a simple arithmatic operations to simplify the solution of some issues through set theory. In this paper, the foundations of the algorithms are introduced first; then the algorithms are described and analyzed in detail; finally, the meaning of the research of data structure and algorithms in application are discussed. |
