Detailed Description

template<typename TInputImage, typename TOutput = double>
class itk::GaussianBlurImageFunction< TInputImage, TOutput >

Compute the convolution of a neighborhood operator with the image at a specific location in space, i.e. point, index or continuous index. This class is templated over the input image type.

See Also: NeighborhoodOperator; ImageFunction
