Abstract
To improve the discrimination power of color-indexing techniques, we e ncode a minimal amount of spatial information in the index, We tessela te each image with five partially overlapping, fuzzy regions, In the i ndex. for each region in an image, we store its average color and the covariance matrix of the color distribution. A similiarity function of these color features is used to match query images with images in the database. In addition, we propose two measures to evaluate the perfor mance of image-indexing techniques. We present experimental results us ing an image database which contains more than 11,600 color images.
