摘　　要：提出一种相对势能分水岭算法,通过计算分水岭的相对势能,并与预先设定的阈值进行比较,去掉不必要的细节,得到重要轮廓信息.在快速分水岭的模型上引入该方法,能够有效抑制过度分割,避免再进行区域融合,从而提高了效率.与原有区域融合算法相比,该算法的运算效率提高了14.3%,明显地改善了过度分割的现象.A watersheds algorithm for relative potential energy is presented. The presented algorithm calculates the relative potential energy of watersheds and compares them with the preestablished thresholds to remove the unnecessary details and get the important contour information. This method is introduced on the basis of the fast watersheds model As a result, over-segmentation is effectively restrained, region fusing is avoided and the efficiency improved accordingly. Experimental results have shown that, compared with the original region-fusing algorithm, the efficiency has increased by 14.3 %, and that the over-segmentation phenomenon has been obviously improved.
