程序功能为将bmp彩色图片中的背景去除，留下图片的主要内容。该程序采用graph-based的图像分割算法，分割效果良好。

在命令行下通过传递参数运行：ESegment sigma k min input output

其中：ESegment为编译得到的程序名；

sigma为平滑系数，一般取0.5～2之间的值；

k一般取图片长、宽（像素）之间的值；

min表示分割出的最小块的大小，取正整数即可

input为输入的bmp图片名

output为输出的bmp图片名-procedures bmp function of the color of the background of the pictures removed, leaving the main content of photographs. The program uses a graph-based algorithm for image segmentation, segmentation results. The command line operation by passing parameters : ESegment sigma k min input output which : ESegment compiler for the procedure; sigma for smoothing coefficient, generally the 0.5 ~ between the two values; k general admission Photo length, width (pixels) between the value; min said segmentation of the small size, can take positive integer input for the importation of bmp images were output to output from the bmp Photo
