Detailed Description

template<class TPixel, unsigned int VDimension = 2, class TAllocator = NeighborhoodAllocator<TPixel>>
class itk::SobelOperator< TPixel, VDimension, TAllocator >

A NeighborhoodOperator for doing Sobel operation at a pixel.

SobelOperator's coefficients are a tightest-fitting convolution kernel for calculating the laplacian value at a pixel. SobelOperator is a directional NeighborhoodOperator that should be applied to a Neighborhood or NeighborhoodPointer using the inner product method. To create the operator, you need:

1) Set the direction 2) call CreateOperator() For example, the Sobel Operator in vertical direction is -1 -2 -1 0 0 0 1 2 1 while the Sobel Operator in horizonal direction is -1 0 1 -2 0 2 -1 0 1

The Sobel Operator in the Nth dimension can be calculated accordingly.
