| 摘 要： | 本文提出并分析了2DRE四叉树到栅格结构的变换算法。这一算法可看作栅格—2DRE四叉树变换算法的逆变换,但不是它的“反演”,而是采用了较为简洁的求交集运算以及栅格—2DRE四叉树变换算法中的编码转换方法,使得这一算法的实现更加有效,且避免了在图像较大而内存较小的情况下可能发生的“溢出”等矛盾。

| Abstract: | This paper advances and analyses an algorithm converting 2DRE quadtree to. raster. The algorithm can be served as the inverse operation of raster to 2DRE quadtree, but it is not direct inversion, instead, it takes other simpler measur i.e. intersection of 2DRE quadtree and code transforming method in Raster to Quadtree conversion, to make the algorithm more effective. It can also avoid possible trouble of memory overflow caused by the operation on bigger images in smaller memory. |
