使用高效的c均值聚类算法的图象阈值化方法
THRESHOLDING OF IMAGES USING AN EFFICIENT c-MEAN CLUSTERING ALGORITHM
-
摘要: Otsu(1979)的阈值化法被认为是一种良好的图象分割方法。本文提出一个适合图象分割的高效的c均值聚类算法。它与Otsu法有完全相同的分割结果,但计算时间约减少了一个数量级。

Abstract: Otsu s method (1979) is considered as a good thresholding method for image segmentation. In this paper, an efficient c-mean calustring algorithm which is suitable for image segmentation is proposed. It yields th came results as Otsu s method, but its computational time is about one order of magnitude less than that of Otsu s method. -
