| 摘 要： | 为解决谷物外观品质检测过程中获取图像的籽粒粘连问题，提出了一种基于先验知识的流域分割算法。首先，设定合理的区域面积阈值Ath，标记并去除图像中的单个籽粒区域，结果记为M；然后，设定有效腐蚀次数Eth，对粘连籽粒区域进行流域分割，结果记为Mc；最后，取Ms与Mc的并集，作为分割结果。试验结果表明，该算法分割效果较好，分割精度达到95．4％。 |

| Abstract: | A new watershed algorithm based on priori knowledge is presented in this paper, which was adapted to paddy imag e segmentation. Firstly, single seed regions are marked and removed from the clu stering paddy image according to single area threshold ( A th ), and the result image is marked M s . Then, the clustering seed regions are segmented by watershed algorithm according to effective erosion degree threshold ( E th ), and the segmented image is marked M c . Finally, the union of M s and M c is taken as the result image. The experimental results showed t hat the method was valid and efficient, and its precision reached 95.4%. |
