Multiscale Methods in Astronomy
Jean‐Luc Starck · 2006
Wavelets have been used extensively for several years now in astronomy for many purposes, ranging from data filtering and deconvolution, to star and galaxy detection or cosmic ray removal. We review in this paper a range of methods and applications. A recent method, the ridgelet transform is also described, and we show its interest when the data present anisotropic features.
