Multi-scale CLEAN for Fourier-based hard x-ray solar imaging

Volpara, Anna; Piana, Michele; Maria Massone, Anna +1 more

Multi-scale deconvolution is an ill-posed inverse problem in imaging, with applications ranging from microscopy, through medical imaging, to astronomical remote sensing. In the case of high-energy space telescopes, multi-scale deconvolution algorithms need to account for the peculiar property of native measurements, which are sparse samples of the…
