The key features that are in the chameleon are:

- The chameleon method determines the pair of similar sub-clusters that can be connected with other clusters. It also finds the closeness of the clusters from one another.

- The chameleon with the above property overcomes the limitation that is present in agglomerative hierarchical model.

- It uses different methods to take the internal characteristics of the clusters and matches with those which are already present.

- It doesn't depend on static model that is supplied by the user and uses automated functions to perform the merging of the clusters that are already associated in the cluster.   _{Your Comment}
