Paper Abstract

The Scaling-Index-Method (SIM) has been extended by applying weighting functions which take into account the information available on the noise characteristics. The transformation of an image by applying the weighted Scaling-Index-Method yields a measure which depends on the local correlation of the image pixels and the noise structure in the image. In nuclear medicine imaging, the methods based on the SIM enables to extract sources superimposed by strong noise or to discriminate real sources from tomographic artifacts.
