如果想要保存分割结果，可以使用matplotlib库中的imsave函数来保存图像。

例如，可以在代码中添加以下语句来保存Example 1中的分割结果：

plt.imshow(mark_boundaries(img, segments))
plt.contour(roi, contours=1, colors='red', linewidths=0.5)
plt.axis('off')
plt.savefig('example1.png')  # 保存图片
plt.show()

这样就会在当前路径下生成一个名为example1.png的图片文件，其中包含分割结果和ROI边界。需要保存Example 2的分割结果时，也可以类似地添加保存语句。
