| 摘 要： | 用分水岭方法进行图像分割时,容易造成图像的过度分割.为了克服这种缺点,本文提出了改进的图像分水岭分割的方法.该方法先用改进的中值滤波对图像进行预处理,在去除噪声的同时很好的保持物体轮廓和细节;以传统标记提取为基础,以标记点为区域极小值对图像进行分水岭分割.实验结果显示,该方法能很好地抑制过度分割,使分割得到了较好的效果.

| Abstract: | Watershed based image segmentation has the drawback of over-segmentation. To overcome the drawback, a method of improved watershed segmentation algorithm is proposed in this paper. Important region contours and details are preserved while most of the noise are removed by means of improved median filter. Based on classical marker extracting, the pretreated image is segmented by using marker point as the regional minimum. Some real examples are given and the results show that this method is powerful to restrain the over-segmentation and has a good effect on segmentation. |
