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. … 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 for approximation guarantees), and Monte Carlo algorithms.

WebThe main obstacle was that the discrete circular convolution (which also has negative indices) was incompatible with the provided definition of the inverse Fourier transform of the lowpass filter, which lead to a flawed but somehow recognizable result. It is mirrored which gave us the hint for changing sides of the filter. Files
