Abstract

We address in this paper the deconvolution issue for radiointerferometric multispectral images. Whereas this problem has been widely explored in the recent literature for single images, a few algorithms are able to reconstruct multispectral images (three-dimensional images) [1], [2]. We propose in this paper two new distributed algorithms based on the optimization methods ADMM and projected gradient (PG) for the reconstruction of radio-interferometric multispectral images. We present an original distributed architecture and a comparison of their performance on a quasi-real data cube.
