A dynamic weights OWA fusion for ensemble clustering

Abstract

In this work, a new image segmentation algorithm is introduced. The proposed algorithm combines the results of an hybrid clustering ensemble. The ensemble clustering is composed of fuzzy c-means (FCM) algorithm and fuzzy local information c-means (FCM_S1 and FCM_S2) algorithms with different values of the neighbors effect. The consensus technique is performed by the ordered weighted averaging (OWA) method. The weight attributed to each classifier can be modified during the process of classification and is determined by the classifier results of the pixel neighbors classification. Dynamic weights give the method the ability to select the temporal best performance during the classification process. Experiments performed on a synthetic image, and real images show that the proposed algorithm is effective and efficient and provides good noise elimination effect.
