Split bregman algorithm
WebSplit Bregman methods are popular iterative methods for the solution of large-scale minimization problems that arise in image restoration and basis pursuit. WebAs already discovered in [28], the Split Bregman algorithm (13) is just the AL algorithm (11) with the only difference that in (13) the iterates b(k) are scaled by γ. Hence, we can 1 (k) …
