Abstract: This paper proposes a color image retrieval algorithm using main color, clustering index. It quantifies the image using MPEG-7 visual content description, selects the main color and its percentage as the color characteristics, establishes the clustering index database based on the main colors. The similarity between image is computed by using the color characteristics and image fast retrieval is obtainable by using the clustering index. Experimental results show that the proposed image retrieval is more efficient in retrieving the user interested images with faster retrieval speed.
