Abstract: The hidden Markov model (HMM) is a generative model that treats sequential data under the assumption that each observation is conditioned on the state of a discrete hidden variable that evolves in time as a Markov chain. The first is that it isn’t a clustering algorithm, it is a partitioning algorithm. Therefore, fuzzy clustering methods are particularly suitable for the segmentation of medical images. 2) Unlike k-means where data point must exclusively belong to one cluster center here data point is assigned. c-means and fuzzy c-means clustering are two very popular image segmentation algorithms. But, this conventional algorithm is calculated by iteratively minimizing the distance between the pixels and to the cluster centers. How does all this stuff help with image segmentation? The motivation behind image segmentation using k-means is that we try to assign labels to each pixel based on the RGB (or HSV) values.
