Abstract

In this paper, we propose a new heuristic algorithm for three-dimensional image reconstruction from coded aperture images based on simulated annealing (SA). Since the coded aperture can view the object with a large solid angle, it can provide some tomographic resolution for three-dimensional object. We propose to use a heuristic algorithm to remove the defocused artifacts and to improve the tomographic resolution. We also propose a fast algorithm to reduce the large computation cost of the heuristic algorithm.
