摘要
整数维度在生活中并不适用,分形维数能够更加准确的表示出维度。许多情况下分形维数的计算是对二维数字图像分析得到的,本文介绍了分形维数的基本概念以及原理,利用MATLAB的图像处理和数值计算功能,针对二维数字图像的特点,探讨采用计盒维数计算图像的分形维数的方法,并提出一种可以减少运算时间的方法,结果证明该方法基本可以保证结果的准确性,同时减少程序运算的时间。
The integer dimension is not applicable in real life,the fractal dimension can represent the dimension more accurately.The calculation of the fractal dimension is based on the digital images in many cases,this paper describes the basic concept of the fractal dimension,discussing the method to calculate the box dimension according to the characteristics of digital image by the image processing and numerical calculation on MATLAB,and propose a method to reduce the computing time to meet the needs of real-time.The result shows it can basically guarantee the accuracy of results and reduce the computing time.
