  • Bilevel Parameter Learning for Higher-Order Total Variation Regularisation Models 

    De, los Reyes JC; Schönlieb, C-B; Valkonen, T (SpringerJournal of Mathematical Imaging and Vision, 2016-06-01)
    We consider a bilevel optimisation approach for parameter learning in higher-order total variation image reconstruction models. Apart from the least squares cost functional, naturally used in bilevel learning, we propose ...
