Abstract

In content-based image indexing and retrieval (IIR), hue component histograms of images are widely used for indexing the images in an image database. It is to retrieve all color images whose distance between hue distributions are within some threshold distance of the query image. Edit distance has been successfully used as a similarity measure. Our earlier algorithm O(b²) computing the edit distance between two angular histograms, where b is the number of bins in the hue histogram, tends to be too slow for users to wait for the outputs when applied to every image in the database. For this reason, we design two filtration functions that eliminate most color images from consideration as possible outputs quickly and exact edit distances are only computed for those remaining images. We are still guaranteed to find all similar hue distributions and the filtration technique gives significant speeds-ups.
