Detailed Description

template<unsigned int NDimension>
class itk::GradientMagnitudeSigmoidFeatureGenerator< NDimension >

Generates a feature image by computing the gradient magnitude of the input image and applying a sigmoid transformation to it.

The typical use of this class would be to generate the edge-map needed by a Level Set filter to internally compute its speed image.

SpatialObjects are used as inputs and outputs of this class.

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::FeatureGenerator< NDimension >.
