Section 6: Irreversible Data Compression

Practical image compression

Two basic phenomena contribute to our ability to compress images in practice. First, that typical images of relevance tend to be far from random—indeed they often involve quite limited numbers of distinct objects. And second, that many fine details of images go unnoticed by the human visual system (see the next section).
