Abstract

MOST pictures of visual interest contain a large amount of detailed information. Studies have shown that a great deal of these data can be filtered out without destroying a subject's or a machine's ability to recognise even quite complex objects1–4. The resulting benefits are economy of memory store and considerable flexibility in the shape and detail of objects classified as the same.
