Segment N-dimensional grayscale images into c classes using efficient c-means or fuzzy c-means clustering algorithm

c-means and fuzzy c-means clustering are two very popular image segmentation algorithms. While their implementation is straightforward, if realized naively it will lead to substantial overhead in

A fast implementation of the well-known fuzzy c-means clustering algorithm

When you need to clusterize data, fuzzy c-means is an appealing candidate, being it more robust and stable than the k-means clustering algorithm. This implementation is faster than that found in the

gryascale and color image segmentation

A fast and robust fuzzy c-means clustering algorithms, namely FRFCM, is proposed. The FRFCM is able to segment grayscale and color images and provides excellent segmentation results.
