用于图象表示的四元代码树

The Quadcodetree Used to Represent Image

本文介绍了四元代码和四元代码树的概念,讨论了用四元代码树表示图象中区域的存储形式,并证明了这种存储形式是很有效的.给出了简单连通区域的四元代码树表示和点阵表示相互之间进行转换的算法.

This paper introduces the concept of quad-cod and quadcodetree.The storage form of aquadcodetree represented region in image isdiscussed,and is shown to be efficient.Thealgorithms to make the conversion betweenquadcodetree representation of a simply-connec-ted region and array are presented.
