WebMinimization functionals related to Euler's elastica energy has a broad range of applications in computer vision and image processing. This paper proposes a novel Euler's elastica and curvature-based variational model for image restoration WebBregman Iteration Bregman iteration [1],[22],[28],[35] is a technique for solving constrained convex minimization problems of the form where J and H are (possibly nondifferentiable) convex functionals on defined on a Hilbert space. We assume there exists u minimizing H for which H(u) = 0 and J(u) < ∞. The key idea is the Bregman distance. WebIn the experiments, the minimizer of AROF μ (c 1 − c 2) has been computed by the standard Split-Bregman algorithm. Observe that we are imposing the condition c 1 > c 2 at each step. This condition is guaranteed if initially it is so. ... Moreover, this property is preserved at each iteration. The algorithm reads as follows: express church
