MeDuSa: a multi-draft based scaffolder
Emanuele Bosi,Beatrice Donati,Marco Galardini,Sara Brunetti,Marie-France Sagot,Pietro Liò,Pierluigi Crescenzi,Renato Fani,Marco Fondi +8 more
TL;DR: MeDuSa formalizes the scaffolding problem by means of a combinatorial optimization formulation on graphs and implements an efficient constant factor approximation algorithm to solve it, which does not require either prior knowledge on the microrganisms dataset under analysis or the availability of paired end read libraries.
Journal ArticleDOI
Reconstruction of 4- and 8-connected convex discrete sets from row and column projections
TL;DR: The problem of reconstructing a discrete two-dimensional set from its two orthogonal projection (H,V) when the set satisfies some convexity conditions can be solved in polynomial time also in a class of discrete sets which is larger than the class of convex polyominoes, namely, in theclass of 8-connected convex sets.
Journal ArticleDOI
An algorithm reconstructing convex lattice sets
Sara Brunetti,Alain Daurat +1 more
TL;DR: The main result of this paper is a polynomial-time algorithm solving the reconstruction problem for the “Q-convex” sets, a new class of subsets of Z2 having a certain kind of weak connectedness.
Journal ArticleDOI
Discrete tomography determination of bounded lattice sets from four X-rays
TL;DR: Hajdu (2005) proved that for any fixed rectangle A in Z^2 there exists a non trivial set S of four lattice directions, such that any two subsets of A can be distinguished by means of their X-rays taken in the directions in S.
Journal ArticleDOI
Stability results for the reconstruction of binary pictures from two projections
Andreas Alpers,Sara Brunetti +1 more
TL;DR: Several theorems are proved showing that reconstructions from two directions closely resemble the original picture when the noise level is low and the originalpicture is uniquely determined by its projections.
