中文说明：
采用分水岭算法对图像进行分割。直接对图像进行分水岭算法，效果并不理想。本方法使用形态学重建技术对前景对象进行标记，求局部极大值，最终将分割好的图像进行伪彩色显示，让结果更加明显。适用于较复杂的图像分割处理。
English Description：
Watershed algorithm is used to segment the image. The effect of watershed algorithm is not ideal. In this method, morphological reconstruction technology is used to mark the foreground object, and the local maximum is calculated. Finally, the segmented image is displayed in pseudo color to make the result more obvious. It is suitable for complex image segmentation.
