Resumo

Existing Fast Marching methods solve the Eikonal equation using a continuous (first order) model to estimate the accumulated cost, but a discontinuous (zero order) model for the traveling cost at each grid point. As a result the estimate of the accumulated cost (calculated numerically) at a given point will vary based on the direction of the arriving front, introducing an anisotropy into the discrete algorithm even though the continuous PDE is itself isotropic. To remove this anisotropy, we propose two very different schemes. In the first model we utilize a continuous interpolation of the traveling cost, which is not biased by the direction of the propagating front. In the second model we upsample the traveling cost on a higher resolution grid to overcome the directional bias. We show the significance of removing the directional bias in the computation of the cost in some applications of fast marching method, demonstrating that both methods make the discrete implementation more isotropic in accordance with the underlying continuous PDE. We also compare the accuracy and computation time of our proposed methods with the existing state of the art fast marching techniques to demonstrate the superiority of our method.
