An extension module implimenting the fast marching method
Project description
scikit-fmm is an extension module which implements the fast marching method.
The fast marching method is used to model the evolution of boundaries and interfaces in a variety of application areas.
scikit-fmm is a simple module which provides two functions: distance(phi, dx=1.0) and travel_time(phi, speed, dx=1.0).
The functions calculate the signed distance and travel time to an interface described by the zero contour of the input array phi.
>>> import skfmm >>> phi = [-1,-1,-1,1,1,1] >>> skfmm.distance(phi) array([-2.5, -1.5, -0.5, 0.5, 1.5, 2.5])
>>> skfmm.travel_time(phi, [2,2,2,2,2,2]) array([ 1.25, 0.75, 0.25, 0.25, 0.75, 1.25])
The input array can be of 1, 2, 3 or higher dimensions and can be a masked array.
