Having analyzed the drawbacks of image retrieval based on K-means algorithm,a novel image retrieval method based on improved K-means algorithm was presented in this paper.Firstly,computed the distance of every two color histograms of all color histograms in the image feature database.Then,took the two feature vectors which the distance between them is the maximum in the database,as the first two initial centroids,and found all correct initial centroids,and clustered according to the initial class centroids.Finally,started image retrieval.Experimental results demonstrate that the proposed method is efficient.
