本工具包含三个主要的函数：

This package contains 3 main finder functions:

ap_finder.m - 确定二值图像中粒子簇的面积和周长，并以单独的数组返回每个粒子簇的参数。主要用于绘制分形颗粒聚集体的面积和周长图。注意，周长是通过将簇在每个方向上扩展1个像素来确定的，而不是通过默认的MATLAB例程来确定的。

ap_finder.m - this determines the area and perimeters of particle clusters in a binary image, and returns each in a separate array. Mainly for making area vs. perimeter plots for fractal particle aggregates. Note, the perimeter is determined by expanding the clusters by 1 pixel in every direction, not by the default MATLAB routine.

conn_finder.m - 此函数确定图像连接组件（即簇集）的多个几何方面特性，例如平均簇集区域、每个簇集的质量中心坐标、每个簇集的回转半径和图像的相关长度。

conn_finder.m - this function determines several geometric aspects of the connected components of the image (i.e. the clusters), such as average cluster area, centre of mass coordinates for each cluster, the gyration radius of each cluster, and the correlation length of the image.

D_finder.m - 使用缩放/盒计数方法，找到图像中每个簇的Hausdorff分形维数。

D_finder.m - find the Hausdorff fractal dimension of each cluster in the image, using the scaling/box counting method.

本工具包包含了一些与算法相关的简短数学说明与注解。

A short mathematical note is included on the methods used.
