Objective To enhance the accuracy of the content-based image retrieval.Methods The color histogram feature was extracted as retrieval feature by using fuzzy quantization method in HSV color space.On this basis,the features of images in the image base formed many clusters by two-stage cluster method.In the image retrieval stage,the relevant images were returned by comparing the features between query image and the centre of each cluster.Results Experimental results showed that this method could improve the recall and precision of query image,and improved the rank or the relevant image in the retrieval results.Conclusion This image retrieval method is reasonable and effective,and its retrieval results are satisfactory.
