|Abstract:||In this paper, two framelet based disconsolation algorithms are proposed. The basic idea of frame let based approach is to convert the disconsolation problem to the problem of in painting in a frame domain by constructing a frame let system with one of the masks being the given (discrete) convolution kernel via the unitary extension principle of , as introduced in [6-9]. The first algorithm unifies our previous works in high resolution image reconstruction and infra-red chopped and nodded image restoration, and the second one is a combination of our previous frame-based disconsolation algorithm and the iterative shareholding algorithm given by [14,16]. The strong convergence of the algorithms in infinite dimensional settings is given by employing proximal forward-backward splitting (PFBS) method. Consequently, it unifies iterative algorithms of infinite and finite dimensional setting and simplifies the proof of the convergence of the algorithms of . © 2010 by AMSS, Chinese Academy of Sciences.|
