摘　　要：根据分水岭变换的模拟浸水原理,笔者设计并实现了一种新的、快速有效的分水岭 图像分割算法,用于对粘连目标物进行分割。该算法把图片中各个粘连物体视做一个个的盆地,只需扫 描初始图片中各个象素的四连通和盆地的边缘情况即可,且其简单明了,执行速度快,又达到了对目标 图像进行有效分离的目的,成功有效的解决了由于目标物体粘连而造成的不便和对后续处理的干扰等 问题,是一种切实可行的图像分割方法。In this paper, the mathematical morphology, an efficient watershed segmented algorithm based on watershed transformation is presented. Initially, the objects are viewed as some catchment basins. In this algorithm, the 4-conn and the edge of catchment basins are the only things that need to be considered. Based on the gray level of image, catchment basins dilate gradually, at the same time, new basins are discovered. In the end, as the dam is constructed, the touched objects are separated from each other efficiently. The algorithm can successfully solve the inconvenience brought by the touched objects and find an efficient way for the follow-up work. It is a practicable method for the separation of touched objects.
