Moreau F., Gibert D., Holschneider M., Saracco G. Wavelet analysis of potential fields (348K, ps-file, compressed, uuencoded) ABSTRACT. It is shown how a continuous wavelet technique may be used to locate and characterize homogeneous point sources from the field they generate measured in a distant hyperplane. For this a class of wavelets is introduced on which the Poisson semi-group essentially acts as a dilation.
