Color image retrieval based on mixture approximation and color region matching

The paper introduces the extension of the color image retrieval method based on the approximation of the perceptual parameters. The proposed solution enables effective search for similar images regardlessly of the applied compression scheme not only taking into account the color palette and the presence of regions of the homogenous color within the image, but also their spatial arrangement. The proposed method utilizes the Gaussian Mixture Modeling combined with the Bilateral Filtering approach along with color matching method based on dominant region color. The evaluated results show that satisfactory retrieval results can be obtained regardlessly to applied compression schemes, preserving the spatial arrangement of the color regions in evaluated results.
