Detailed Description

template<class TInput, class TOutput>
class itk::FastMarchingImageFilterBase< TInput, TOutput >

Fast Marching Method on Image.

The speed function can be specified as a speed image or a speed constant. The speed image is set using the method SetInput(). If the speed image is NULL, a constant speed function is used and is specified using method the SetSpeedConstant().

If the speed function is constant and of value one, fast marching results is an approximate distance function from the initial alive points.

There are two ways to specify the output image information ( LargestPossibleRegion, Spacing, Origin):

it is copied directly from the input speed image
it is specified by the user. Default values are used if the user does not specify all the information.

The output information is computed as follows.

If the speed image is NULL or if the OverrideOutputInformation is set to true, the output information is set from user specified parameters. These parameters can be specified using methods

Else the output information is copied from the input speed image.

Implementation of this class is based on Chapter 8 of "Level Set Methods and Fast Marching Methods", J.A. Sethian, Cambridge Press, Second edition, 1999.
