IMAGE CODING

Fractal-based image coding is based on the theory of iterated function systems (IFS). An image may be represented by a dynamical system, known as a fractal transform, whose attractor is close to the image being coded. For natural images, the parameters of such a dynamical system…

Hierarchical subband coding has been very successful over recent years in the compression of still and moving images. In particular, set-partitioned hierarchical subband coding schemes have been found to yield excellent results, yet have low complexity—a phenomenon which has pav…
