A Hierarchical Algorithm for Fast Backprojection in Helical Cone-Beam Tomography
Existing algorithms for exact helical cone beam (HCB) tomographic reconstruction involve a 3-D backprojection step, which dominates the the computational cost of the algorithm. We...

Generalizing DPOP: Action-GDL, a new complete algorithm for DCOPs
In this paper we propose a novel message-passing algorithm, the so-called Action-GDL, as an extension to the Generalized Distributive Law algorithm (GDL) [1] to efficiently solve...
