Scientific paper
The regularized reconstruction algorithm {Interactive Deconvolution with Error Analysis} (IDEA) is presented. One of its main advantages is to control the error propagation and to provide an estimation of the quality of the deconvolved image. IDEA is compared with two popular probabilistic methods: Richardson-Lucy and Maximum Entropy. These three methods are applied to Hubble Space Telescope aberrated images: SN 1987A and the jets of M 87 and 3C 66B. Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555
