We study the convergence behavior of a class of projection methods for solving convex feasibility and optimization problems. We prove that the algorithms in this class converge to solutions of theâ€¦ (More)

Image reconstruction from projections suffers from an inherent difficulty: there are different images that have identical projections in any finite number of directions. However, by identifying theâ€¦ (More)

The general problem that we are trying to solve is sequential image-signal interpretation with the applicability of our work to the improvement of hearing aids. As part of this bigger problem, weâ€¦ (More)

We propose a new direct labeling approach to electron tomography of biological macromolecules, using Gibbs priors and the marginal posterior mode (MPM) estimator. The aim is to produce a tessellationâ€¦ (More)

To facilitate the retrieval of volume images from a biomedical database (e.g., images of proteins from a macromolecular database), it is necessary to obtain concise descriptors of the images.â€¦ (More)

The co-existence of different states of a macromolecular complex in samples used by three-dimensional electron microscopy (3D-EM) constitutes a serious challenge. The single particle method appliedâ€¦ (More)
