Paper Abstract

A means of extending wavelets and multiresolution decompositions to the finite field case is demonstrated, which uses the lifting scheme developed by W. Sweldens. The advantages and disadvantages of using finite field discrete wavelet transforms in coding schemes are discussed, and the binary case is examined in detail. The use of the new scheme is expected to pay off in practice by permitting fast computation in small memory on crude platforms; in particular, possible applications to downlinking satellite- borne SAR systems are discussed.
