Abstract
The use of color information for image retrieval has been used widely in many content-basedretrieval system with some success. However, histogram-based color retrieval techniques su#er from a lack of important spatial knowledge. We discuss a technique of integrating color information with spatial knowledge to obtain an overall impression of the image. The technique involves three steps: the selection of a set of representative colors, the analysis of spatial information of the selectedcolors, and the retrieval process based on the integratedcolor-spatial information. Two color histograms are used to aid in the process of color selection. After deriving the set of representative colors, spatial knowledge of the selectedcolors is obtained using a maximum entropy discretization with event covering method. Aretrieval process is formulated to make use of the spatial knowledge to retrieve relevant images. A prototype image retrieval system has been implemented on the Unix system. It is tested on an image database consisting of 260 images. The result shows substantial improvement over the histogram-basedcolor retrieval methods.
