On the Stable Resolution Limit of Total Variation Regularization for Spike Deconvolution

10 Mar 2020 Da Costa Maxime Ferreira Chi Yuejie

The stability of spike deconvolution, which aims at recovering point sources from their convolution with a point spread function (PSF), is known to be related to the separation between those sources. When the observations are noisy, it is critical to ensure support stability, where the deconvolution does not lead to spurious, or oppositely, missing estimates of the point sources... (read more)
