This paper introduces a new method for color blood cell image segmentation based on FCM algorithm. By transforming the original blood microscopic image to indexed image, and by doing the colormap, a fuzzy apparoach to obviating the direct clustering of image pixel values, the quantity of data processing and analysis is enormously compressed. In accordance to the inherent features of color blood cell image, the segmentation process is divided into two stages. (1)confirming the number of clusters and initial cluster centers; (2) altering the distance measuring method by the distance weighting matrix in order to improve the clustering veracity. In this way, the problem of difficult convergence of FCM algorithm is solved, the iteration time of iterative convergence is reduced, the execution time of algarithm is decreased, and the correct segmentation of the components of color blood cell image is implemented.
本文介绍了一种基于FCM算法的彩色血细胞图像分割新方法。通过将原始血液显微图像转换为索引图像,并进行颜色映射,采用模糊方法避免图像像素值的直接聚类,极大地压缩了数据处理和分析量。根据彩色血细胞图像的固有特征,分割过程分为两个阶段。(1)确定聚类数和初始聚类中心;(2)通过距离加权矩阵改变距离测量方法,以提高聚类准确性。这样,解决了FCM算法收敛困难的问题,减少了迭代收敛的迭代次数,降低了算法的执行时间,并实现了彩色血细胞图像各成分的正确分割。
