Energy-minimization based discrete tomography reconstruction method for images on triangular grid

Abstract

In this paper binary tomography on the triangular grid is addressed. We use three and six natural projections according to the structure of the grid. We propose an energy-minimization method based on the simulated annealing algorithm to reconstruct the original images. Our method is shown in four regular hexagon shaped test images of approximately 4000 pixels. © 2012 Springer-Verlag.
