Abstract :
The authors present a robust mixture decomposition technique that automatically finds a compact representation of the data in terms of categories, and apply it to the problem of organizing databases for efficient retrieval. The time taken for retrieval is shown to be an order of magnitude smaller than that of exhaustive search methods. The proposed scheme is tested on images from the VisTex texture image database
