Detailed Description
template<class TPixel, unsigned int VDimension = 2, class TAllocator = NeighborhoodAllocator<TPixel>>
class itk::GaussianDerivativeOperator< TPixel, VDimension, TAllocator >
A NeighborhoodOperator whose coefficients are a one dimensional, discrete derivative Gaussian kernel.
GaussianDerivativeOperator can be used to calculate Gaussian derivatives by taking its inner product with to a Neighborhood (NeighborhooIterator) that is swept across an image region. It is a directional operator. N successive applications oriented along each dimensional direction will calculate separable, efficient, N-D Gaussian derivatives of an image region.
GaussianDerivativeOperator takes three parameters:
(1) The floating-point variance of the desired Gaussian function.
(2) The order of the derivative to be calculated (zero order means it performs only smoothing as a standard itk::GaussianOperator)
(3) The "maximum error" allowed in the discrete Gaussian function. "Maximum errror" is defined as the difference between the area under the discrete Gaussian curve and the area under the continuous Gaussian. Maximum error affects the Gaussian operator size. Care should be taken not to make this value too small relative to the variance lest the operator size become unreasonably large.
References: The Gaussian kernel contained in this operator was described by Tony Lindeberg (Discrete Scale-Space Theory and the Scale-Space Primal Sketch. Dissertation. Royal Institute of Technology, Stockholm, Sweden. May 1991.).

Sets a limit for growth of the kernel. Small maximum error values with large variances will yield very large kernel sizes. This value can be used to truncate a kernel in such instances. A warning will be given on truncation of the kernel.

| void itk::GaussianDerivativeOperator< TPixel, VDimension, TAllocator >::SetNormalizeAcrossScale | ( | bool | flag | ) | [inline] |
Set/Get the flag for calculating scale-space normalized derivatives. Normalized derivatives are obtained multiplying by the scale parameter t.
Definition at line 146 of file itkGaussianDerivativeOperator.h.
| void itk::GaussianDerivativeOperator< TPixel, VDimension, TAllocator >::SetOrder | ( | const unsigned int | order | ) | [inline] |
Sets the order of the derivative.

| void itk::Neighborhood< TPixel, VDimension, TAllocator >::SetRadius | ( | const unsigned | long | ) | [inherited] |
Overloads SetRadius to allow a single long integer argument that is used as the radius of all the dimensions of the Neighborhood (resulting in a "square" neighborhood).
| void itk::Neighborhood< TPixel, VDimension, TAllocator >::SetRadius | ( | const unsigned long * | rad | ) | [inline, inherited] |
Sets the radius for the neighborhood. Overloaded to support an unsigned long array.
Definition at line 186 of file itkNeighborhood.h.
| void itk::Neighborhood< TPixel, VDimension, TAllocator >::SetRadius | ( | const SizeType & | ) | [inherited] |
Sets the radius for the neighborhood, calculates size from the radius, and allocates storage.

| void itk::Neighborhood< TPixel, VDimension, TAllocator >::SetSize | ( | ) | [inline, protected, inherited] |
Sets the length along each dimension.

| void itk::GaussianDerivativeOperator< TPixel, VDimension, TAllocator >::SetSpacing | ( | const double | spacing | ) | [inline] |
Sets the spacing for the direction of this kernel.
Definition at line 161 of file itkGaussianDerivativeOperator.h.
| void itk::GaussianDerivativeOperator< TPixel, VDimension, TAllocator >::SetUseDerivativeOperator | ( | bool | flag | ) | [inline] |
Set/Get the flag for choosing the implementation. If we choose to use itk::DerivativeOperator, then the derivative Gaussian kernel is calculated as a convolution with the itk::DerivativeOperator of the desired order. Otherwise a polynomial is computed analitically for the derivative of the Gaussian.
Definition at line 133 of file itkGaussianDerivativeOperator.h.
| void itk::GaussianDerivativeOperator< TPixel, VDimension, TAllocator >::SetVariance | ( | const double | variance | ) | [inline] |
Sets the desired variance of the Gaussian kernel.

| unsigned int itk::Neighborhood< TPixel, VDimension, TAllocator >::Size | ( | void | ) | const [inline, inherited] |
More STL-style support.
