This analysis demonstrates improved image reconstruction quality in comparison to sparse modeling techniques.
This paper presents a continuous-time image reconstruction system that incorporates a preconditioning matrix. We demonstrate that the system’s equilibria correspond to an optimal solution of a quadratic programming problem with box constraints. Additionally, we provide numerical evidence demonstrating that the proposed system generates a higher-quality reconstruction image compared to a sparse modeling technique.
