I do not understand what spherical means, and how kmeans and EM are related, since one does probabilistic assignment and the other does it in a deterministic way. While K-Means discovers hard clusters (a point belong to only one cluster), Fuzzy K-Means is a more statistically formalized method and discovers soft clusters where a particular point can belong to more than one cluster with certain probability. Fuzzy clustering is a healthy approach as it considers the cell particles at the edge of image. It was developed by Dunn and improved by Bezdek. This method is frequently used in pattern recognition. Cluster head is selected based on sensor’s location within each cluster, its location with respect to fusion center (FC), its signal-to-noise ratio (SNR) and its residual energy.
