Content-based image retrieval using combination features

Image retrieval based on single feature is already quite mature, how to use these single features effectively is the key issue in improving the effect of the image retrieval. We often use the combination features to solve the problem. In this paper, we use the dynamic weight to combination these single features. Experimental results show that the algorithm using dynamic weight can accurately and efficiently retrieve the target image compared with using the method of using fixed weight. The method using the dynamic weight effectively improves the image retrieval accuracy.
