The dominant color descriptor (DCD) is widely applied in the image retrieval taken as one of MPEG-7 color descriptors. DCD describes the representative color distributions and features in an image or a region of interest through an effective, compact and intuitive format. A novel image retrieval method based on the fixed number's MPEG-7 dominant color descriptor is proposed. The feature extraction process does not need the intervention of the threshold value and the dominant color number is fixed as eight. The histogram intersection algorithm is used to measure features, simplifies the similarity computation complexity. The experiment results show that the precision and recall rate of this method is higher than that of non-fixed number's dominant color retrieval method.
