Which is the best (fastest) algorithm for finding no of clusters for k means while clustering a multi-spectral image, Silhouette value , or Dunn Index or Davies Bouldin index ?

I am using Silhouette value for cluster cohesion evaluation, but finding silhouette for all possible no of clusters makes it slow, so i rather want to find the optimum no of clusters first that exists in the data and then use the silhouette value for further cluster compactness evaluation

Use evalclusters. There are many ways to detect the right number of clusters using this function.
Type help evalclusters for more information.
