Detailed Description

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

A NeighborhoodOperator for performing a directional Sobel edge-detection operation * at a pixel location.

SobelOperator is a directional NeighborhoodOperator that should be applied a NeighborhoodIterator using the NeighborhoodInnerProduct method. To create the operator:

1) Set the direction by calling

 SetDirection 

2) call

 CreateOperator() 

3) You may optionally scale the coefficients of this operator using the

 ScaleCoefficients 

method. This is useful if you want to take the spacing of the image into account when computing the edge strength. Apply the scaling only after calling to

 CreateOperator 

.

The Sobel Operator in vertical direction for 2 dimensions is

 *             -1  -2  -1  
 *             0    0   0 
 *             1    2   1
 *
 * 

The Sobel Operator in horizonal direction is for 2 dimensions is

 *             -1   0   1
 *             -2   0   2 
 *             -1   0   1
 * 

The current implementation of the Sobel operator is for 2 and 3 dimensions only. The ND version is planned for future releases.

The extension to 3D is from the publication "Irwin Sobel. An Isotropic 3x3x3 Volume Gradient Operator. Technical report, Hewlett-Packard Laboratories, April 1995."

The Sobel operator in 3D has the kernel

 * -1 -3 -1   0 0 0  1 3 1
 * -3 -6 -3   0 0 0  3 6 3 
 * -1 -3 -1   0 0 0  1 3 1
 *
 *    x-1       x     x+1
 * 

The x kernel is just rotated as required to obtain the kernel in the y and z directions.
