Wavelet—Galerkin Solutions of Partial Differential Equations
Compactly supported wavelets have proven to be very useful in signal processing, notably in image compression (see Chapter 13 of this book and the references there). The fundamental idea in the application to image compression is to take a digitized image and to use wavelets to provide a multiscale representation of it, and then to discard some information at some scales, and leave information more intact at other scales.
