EdgePicker类中实现了Kirsch、Prewitt、Sobel、Gauss边缘提取算法，并根据MATLAB中的Canny算法实现了Canny算法，BianYuanJianCe.CPP中实现了背景提取。程序中图像的读取、存储用到了ImageMagick库，ImageMagick库的使用方法在ImageMagick.rar中有说明-EdgePicker class implements Kirsch, Prewitt, Sobel, Gauss edge extraction algorithm and, based on MATLAB, the Canny algorithm of the Canny algorithm, BianYuanJianCe.CPP to achieve the background extraction. Program to read the image, store use the ImageMagick library, ImageMagick library to use is illustrated in the ImageMagick.rar
