Clustering using fuzzy C-means (FCM) is a soft segmentation method that has been extensively investigated and successfully implemented in image segmentation. FCM is useful in various aspects, such as the segmentation of grayscale images. However, FCM has some limitations in terms of its selection of the initial cluster center. It can be easily trapped into local optima and is sensitive to noise, which is considered the most challenging issue in the FCM clustering algorithm. This paper proposes an approach to solve FCM problems in two phases. Firstly, to improve the balance between the exploration and exploitation of improved global best-guided artificial bee colony algorithm (IABC). This is achieved using a new search probability model called PIABC that improves the exploration process by choosing the best source of food which directly affects the exploitation process in IABC. Secondly, the fuzzy clustering algorithm based on PIABC, abbreviated as PIABC-FCM, uses the balancing of PIABC to avoid getting stuck into local optima while searching for the best solution having a set of cluster center locations of FCM. The proposed method was evaluated using grayscale images. The performance of the proposed approach shows promising outcomes when compared with other related works.
基于模糊 C 均值(FCM)的聚类是一种软分割方法,已在图像分割中得到了广泛的研究和成功的应用。FCM 在灰度图像分割等方面非常有用。然而,FCM 在初始聚类中心的选择方面存在一些局限性。它很容易陷入局部最优解,并且对噪声很敏感,这被认为是 FCM 聚类算法中最具挑战性的问题。本文提出了一种分两阶段解决 FCM 问题的方法。首先,通过改进全局最佳引导人工蜂群算法(IABC)的探索和开发之间的平衡,来提高算法的性能。这是通过使用一种新的搜索概率模型 PIABC 来实现的,该模型通过选择直接影响 IABC 中开发过程的最佳食物源来改进探索过程。其次,基于 PIABC 的模糊聚类算法(PIABC-FCM)使用 PIABC 的平衡来避免陷入局部最优解,同时搜索 FCM 的最佳聚类中心位置的解决方案。该方法使用灰度图像进行评估。与其他相关工作相比,所提出的方法具有较好的性能。
