| Abstract: | :
In this paper a natural digits based linear quadtree coding technique is introduced, the formulae for computing the natural code (N code) are given and the procedures of generation of N code based quadtrees are discussed and the efficiency comparison between Morton quaternary code and that based on decimals is made by examples. The geometry analysis of the graphics and algebraical rules of the images based on N-code are also presented. |
