Fuzzy c-means (FCM) clustering algorithms have been proved to be effective image segmentation techniques. However, FCM clustering algorithms are sensitive to noises and initialization. They cannot effectively segment cell images with inhomogeneous gray value distributions and complex touching cells. Aiming to overcome these disadvantages, this paper proposes a cell image segmentation algorithm using fractional-order velocity based particle swarm optimization (FOPSO) combined with shape information improved intuitionistic FCM (SI-IFCM) clustering. Iterations are carried out between FOPSO and SI-IFCM to achieve final cell segmentation. Experimental results demonstrate that the proposed algorithm has advantages on cell image segmentation, with the highest recall (90.25%) and lowest false discovery rate (0.28%) compared with the state-of-the-art algorithms.
模糊 C 均值(FCM)聚类算法已被证明是一种有效的图像分割技术。然而,FCM 聚类算法对噪声和初始化很敏感,无法有效地分割灰度值分布不均匀且细胞相互接触复杂的细胞图像。针对这些缺点,本文提出了一种基于分数阶速度的粒子群优化(FOPSO)与改进的直觉模糊 C 均值(SI-IFCM)聚类相结合的细胞图像分割算法。FOPSO 和 SI-IFCM 之间进行迭代,以实现最终的细胞分割。实验结果表明,与现有的先进算法相比,所提出的算法在细胞图像分割方面具有优势,具有最高的召回率(90.25%)和最低的假发现率(0.28%)。
