Binary image reconstruction from a small number of projections and the morphological skeleton

Binary image reconstruction from a small number of projections and the morphological skeleton In binary tomography, the goal is to reconstruct binary images from a small set of their projections. This task can be underdetermined, meaning that several binary images can have the same projections, especially when only one or two projections are given. On the other hand, it is known that a binary image can be exactly reconstructed from its morphological skeleton when all skeletal labels are known. However, if only the skeletal points are given, different labellings yield different reconstructed images. In this paper, we consider a mixture of the above problems, reconstructing a binary image from few projections and the morphological skeleton. We show that the problem is NP-complete, yet a result with low projection and pixel error usually can be achieved, even if only a single projection is available. Three different variants of a method based on Simulated Annealing are developed and compared with respect to reconstruction time and error using artificial binary images. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Annals of Mathematics and Artificial Intelligence Springer Journals

Abstract

In binary tomography, the goal is to reconstruct binary images from a small set of their projections. This task can be underdetermined, meaning that several binary images can have the same projections, especially when only one or two projections are given. On the other hand, it is known that a binary image can be exactly reconstructed from its morphological skeleton when all skeletal labels are known. However, if only the skeletal points are given, different labellings yield different reconstructed images. In this paper, we consider a mixture of the above problems, reconstructing a binary image from few projections and the morphological skeleton. We show that the problem is NP-complete, yet a result with low projection and pixel error usually can be achieved, even if only a single projection is available. Three different variants of a method based on Simulated Annealing are developed and compared with respect to reconstruction time and error using artificial binary images.
