| 摘 要： | 针对传统分水岭算法分割图像后存在的细节不准确问题,提出了一种改进的分水岭算法.此算法将传统分水岭算法和概率相结合,通过有序队列来实现边界的计算,从而得到分水岭.实验证明,这种算法得到的结果更加准确,对人脑MR图像病灶区的分割非常重要.

| Abstract: | As to the problem of inaccurate detail in scheme segmentation,a new method of improved watershed algorithm is proposed.This method combines traditional watershed algorithm and probability,Through ordered queue,boundary is calculated and watershed is obtained.The experiment proves that the precision of this method is very high and very useful to the segmentation of brain MR scheme. |
