采用结构函数法计算材料界面曲线的分形维数，对应的数据应当为结合界面曲线的.jpg格式，各相关参数的介绍在程序内均有注明。(The fractal dimension of the interface curve of the material interface is calculated by the structural function method. The corresponding data should be in the .jpg format of the interface

计算输入图片的分形维数；图片需为jpg的格式；程序通用性强；十分好用；(The fractal dimension can be calculated by inputting any image)
