A uniform preconditioner for a Newton algorithm for total-variation minimization and minimum-surface problems

Xue-Cheng Tai, Ragnar Winther, Xiaodi Zhang +1

Solution methods for the nonlinear partial differential equation of the Rudin-Osher-Fatemi (ROF) and minimum-surface models are fundamental for many modern applications. Many effic…
