A Novel Iterative CT Reconstruction Approach Based on FBP Algorithm. [PDF]
The Filtered Back-Projection (FBP) algorithm and its modified versions are the most important techniques for CT (Computerized tomography) reconstruction, however, it may produce aliasing degradation in the reconstructed images due to projection ...

Projected iterative algorithms with application to multicomponent transport
Projected iterative algorithms for solving constrained symmetric singular linear systems are examined. The symmetry of generalized inverses, the projected standard iterative methods as well as projected conjugate gradient algorithms are investigated.

In this paper, we propose a new iterative algorithm for solving the multiple-sets split feasibility problem (MSSFP for short) and the split equality fixed point problem (SEFPP for short) with firmly quasi-nonexpansive operators or nonexpansive operators ...

Iterative projection algorithms for solving inverse problems [PDF]
Inverse problems abound in the ocean sciences, as they do in almost every area of science and technology. Solutions to inverse problems are notoriously difficult, computationally expensive, and noise sensitive. Iterative projection algorithms have proved to be particularly useful for solving some image reconstruction problems with incomplete data ...

AN ECC-BASED ITERATIVE ALGORITHM FOR PHOTOMETRIC INVARIANT PROJECTIVE REGISTRATION [PDF]
The ability of an algorithm to accurately estimate the parameters of the geometric transformation which aligns two image profiles even in the presence of photometric distortions can be considered as a basic requirement in many computer vision applications. Projective transformations constitute a general class which includes as special cases the affine,
