4th International Symposium on Independent Component Analysis and Blind Signal Separation (ICA03), Nara : Japon

Independent Component analysis of the Cosmic Microwave Background

J-F. Cardoso, J. Delabrouille1, G. Patanchon1

(2003)

This paper presents an application of ICA to astronomical imaging. A first section describes the astrophysical context and motivates the use of source separation ideas. A second section describes our approach to the problem: the use of a noisy Gaussian stationary model. This technique uses spectral diversity and take explicitly into account contamination by additive noise. Preliminary and extremely encouraging results on realistic synthetic signals and on real data will be presented at the conference
