Wavelets and Multiscale Transforms in Astronomical Image Processing

Fionn Murtagh and Jean-Luc Starck

With the requirements of scientific and medical image database support in mind, we describe a range of useful technologies for storage, transmission and display. These new technologies are all based on discrete wavelet or related multiscale transforms. Other important issues include noise modeling, and the innovative use of entropy for information characterization.
