| 摘 要： | 栅格、矢量和四叉树是计算机图象显示和图象处理中三种最常见的数据格式。本文简要介绍了柳格到四叉树、矢量到栅格、栅格到矢量的转换算法。四叉树到矢量的转换最为复杂，虽有现成算法，但很难具体实现。本文给出了一种较为简单又易于实现的算法。

| Abstract: | There has been interest in the use of quadtrees to represent regions in an image. It thus becomesdesiravle to develop efficient methods of conversion between quadtrees and other types of region representations .An algorithm is presented for converting a quadtree representation of region given its boundary in the form of a chain code. And other converting algorithms are discussed in this paper. |
