Detailed Description

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

Generates a feature image by computing the inverse map to the canny edges in the image.

Overview
The class generates features that can be used as the speed term for computing a canny level set. The class takes an input image

Input -> CastToFloat -> CannyEdgeFilter -> InvertFilter

The resulting feature is ideally used as the speed term for a level set segmentation module. The speed feature generated is designed to lock onto edges (which are extracted by the canny filter).

There are two parameters to this feature generator. (1) UpperThreshold/LowerThreshold: These set the thresholding values of the Canny edge detection. The canny algorithm incorporates a hysteresis thresholding which is applied to the gradient magnitude of the smoothed image to find edges. (2) Sigma. Controls the smoothing parameter of the Gaussian filtering done during Canny edge detection. The first step of canny edge detection is to smooth the input with a Gaussian filter. Second derivatives etc are computed on the smoothed image.

SpatialObjects are used as inputs and outputs of this class.
