Fractal theory quantifies these phenomena mainly by ascertaining their fractal dimensions.Box-counting algorithm is the one most practical and also most frequently adopted method.The traditional box-counting algorithm is based on the grid document and has some serious shortcomings,such as the distortion of the image being enlarged,the trivialness of the process and the finite of the iterative degree,etc.The vector box counting algorithm developed in this paper takes vector document as the carrier and has three advantages.

传统的计盒算法是基于栅格文件的方法，由于其存在图像放大后失真、过程繁琐和迭代次数有限等缺陷，因此为了准确简单方便地进行分维计算，开发了一种以矢量文件为载体的矢量计盒算法，并详细阐述了这种算法的数据结构、处理流程和主要函数，同时以Koch曲线、骨肿瘤边界及水系证明了矢量计盒算法的准确性和优越性。
