Nettet4. mar. 2024 · Revisiting Linearized Bregman Iterations under Lipschitz-like Convexity Condition. The linearized Bregman iterations (LBreI) and its variants have received considerable attention in signal/image processing and compressed sensing. Recently, LBreI has been extended to a larger class of nonconvex functions, along with several … Nettetdistance, called split Bregman iteration, was introduced in [33], which extended the utility of the Bregman iteration and the linearized Bregman iteration to minimizations of more general ‘1-based regularizations including TV, Besov norms, and sums of such things. Wavelet-based denoising using the Bregman iteration was introduced in [50],

Nettet26. apr. 2015 · In this paper, we propose an effective reconstruction method based on the linearized Bregman iterative algorithm with sparse regularization (LBSR) for reconstruction. Considering the sparsity characteristics of the reconstructed sources, the sparsity can be regarded as a kind of a priori information and sparse … Nettetkuk1, a linearized Bregman iteration was proposed in [28, 32], which was inspired by the work in [16]. The idea of the linearized Bregman iteration is to combine a fixed point iteration and the Bregman iteration in [27, 32]. Given p0 = u0 = 0, the linearized Bregman iteration is generated by (uk+1 = argmin u∈Rn µ(J(u) −J(uk)−hu −uk ...
