Analysis of FCM Clustering on Pre and Post Iterative relaxed adaptive center weighted median filter in MRI and CT Brain Images


R Vijayarajan and S Muttan

Image de-noising and clustering in medical images are quite complex because of narrow dynamic range and in-homogeneity. Pre processing steps like image de-noising do have influence over the subsequent image processing which misleads further image analysis. In this paper, a new method which incorporates the advantages of adaptive center weighted median filter and hybrid median filter, called Iterative relaxed adaptive center weighted median filter, has been proposed for image de-noising and the influence of such median filtering methods over Fuzzy C-Means Clustering is analyzed in MRI CT images using Cluster Error Index and Average Cluster Error Index. This analysis leads to proper selection of de-noising algorithm for better clustering of image regions.
