Discrete tomography focuses on the problem of reconstruction of binary images (or finite subsets of the integer lattice) from a small number of their projections. In general, tomography deals with the problem of determining shape and dimensional information of an object from a set of projections. From the … See more Discrete tomography has strong connections with other mathematical fields, such as number theory, discrete mathematics, computational complexity theory and combinatorics. In fact, a number of discrete … See more Among the reconstruction methods one can find algebraic reconstruction techniques (e.g., DART or ), greedy algorithms (see … See more • Geometric tomography See more Various algorithms have been applied in image processing , medicine, three-dimensional statistical data security problems, … See more • Euro DT (a Discrete Tomography Wiki site for researchers) • Tomography applet by Christoph Dürr See more WebProblem description. The least-squares formulation of a binary tomography problem is. where A is a tomography matrix of size m times n, b is the tomographic data of size m times 1, and x is a binary image that has grey levels 0 and 1. This problem is NP-hard to solve. We propose to solve the following convex program instead:
WebBinary tomography is concerned with the recovery of binary images from a few of their projections (i.e., sums of the pixel values along various directions). To reconstruct an image from noisy projection data, one can pose it as a constrained least-squares problem. As the constraints are nonconvex, many approaches for solving it rely on either ...
