A Fast Image Retrieval Method based on Color and Improved Mathematical Morphology

Based on detailed analysis oftraditional CBIR technology,thispaper presents a newmethod based on combination of the color and improved mathematical morphology for image retrieval.First of all,the candiate images are selected by using hue histogram among database images.Then,an improved mathematical morphology is used to extract the edge features in the candiate images obtained in the former step.Finally,thecolor histograms built up by edge features pixel dots are used to retrieve the candiateimages,thus obtaining the final retrieving results.Experimenal results show that this method is more efficient and less in time consumption.
