Research on Techniques of Multifeatures Extraction for Tongue Image and Its Application in Retrieval

Algorithm 1

GLA clustering algorithm (GLA algorithm).

Input: Sample points for cluster , Initial cluster center

Output: Clusters

Method:

Input sample points for cluster and Initial cluster center .

Repeat.

Sort every sample points by the principle of proximity.

Recalculate clusters center.

Calculate the distortion value of all sample, until the distortion value is lower than the setting threshold.
