Image Reconstruction Through Regularization by Envelope Guided Conjugate Gradients

, 1994
In this paper we propose a new way to iteratively solve the image reconstruction problem from noisy images or noisy data linearly related to the pixel intensities. This is done by exploiting the relation between Tikhonov regularization and multiobjective

Convex Operators in Vector Optimization: Directional Derivatives and the Cone of Decrease Directions

, 2007
The paper is devoted to the investigation of directional derivatives and the cone of decrease directions for convex operators on Banach spaces. We prove a condition for the existence of directional derivatives which does not assume regularity of the ...

Existence of a Solution for Generalized Vector Variational Inequalities

, 1996
: It is known that vector variational inequality models arises from vector optimization and vector traffic equilibria. In this paper, existence results of a solution for a generalized pre-vector variational inequality and a generalized prequasi -vector ...

Regularization of Ill-Posed Problems by Envelope Guided Conjugate Gradients

, 1997
We propose a new way to iteratively solve large scale ill-posed problems by exploiting the relation between Tikhonov regularization and multiobjective optimization to obtain iteratively approximations to the Tikhonov L-curve and its corner.
