On Iterative Regularization and Its Application
Many existing techniques for image restoration can be expressed in terms of minimizing a particular cost function. Iterative regularization methods are a novel variation on this th...

On the regularity of iterated hairpin completion of a single word
Hairpin completion is an abstract operation modeling a DNA biooperation which receives as input a DNA strand w = xαyα, and outputs w = xαy¯αx, where x denotes the Watson-Cric...

Rates of Asymptotic Regularity for Halpern Iterations of Nonexpansive Mappings
: In this paper we obtain new effective results on the Halpern iterations of nonexpansive mappings using methods from mathematical logic or, more specifically, proof-theoretic te...

Iterative Total Variation Regularization with Non-Quadratic Fidelity
Abstract. A generalized iterative regularization procedure based on the total variation penalization is introduced for image denoising models with non-quadratic convex fidelity ter...
