A new image coding technique for achieving an extremely high compression ratio while producing good image quality is described. The idea is analogous to that used in forensic applications when constructing a composite image of a criminal from a collection of images of facial features. Simply, the input image is segmented into complicated primitives that are coded using a previously constructed database of primitives. A duplicate database is used at the receiver to decode the primitives. The
