Abstract
Sequential fast marching method relies on serial priority queues, which, in turn, imply high complexity for large volumes of data. In this paper, an algorithm to compute the shortest path in the fast marching method for 3D data on graphics processing units devices (GPUs) is introduced. Numerical simulations show that the proposed algorithm achieves speedups of 2\(\times \) and 3\(\times \) compared to the sequential algorithm.
