We deal with the question of uniqueness, namely to decide when an unknown finite set of points in Z 2 is uniquely determined by its X-rays corresponding to a given set S of lattice …

An accurate knowledge of the complex microstructure of a heterogeneous material is crucial for its performance prediction, prognosis and optimization. X‐ray tomography has provided a …
X-ray tomography has provided a non-destructive means for microstructure characterization in three and four dimensions. A stochastic procedure to accurately reconstruct material …

We present a new algorithm for reconstructing binary images from their projections along a small number of directions. Our algorithm performs a sequence of related reconstructions …
In the reconstruction problem of discrete tomography, projections are considered from a finite set ${\mathcal {S}} $ of lattice directions. Employing a limited number of projections …

How to perfectly recover a binary signal from its discrete Fourier transform (DFT) coefficients is studied. The theoretic lower bound and a practical recovery strategy are derived and …

If an unknown finite set C⊂ Z 2 is cut by lines parallel to given directions, then one may count the number of points of C that are intercepted by each line, that is, the projections of C …
Discrete tomography deals with the reconstruction of images from their projections where the images are assumed to contain only a small number of grey values. In particular, there is …
