class itk::DiscreteGradientMagnitudeGaussianImageFunction< TInputImage, TOutput >
Compute the discrete gradient magnitude gaussian of an the image at a specific location in space, i.e. point, index or continuous index. This class computes a single derivative given the order in each direction (by default zero). This class is templated over the input image type.
The Initialize() method must be called after setting the parameters and before evaluating the function.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from itk::ImageFunction< TInputImage, TOutput, TOutput >.

| void itk::DiscreteGradientMagnitudeGaussianImageFunction< TInputImage, TOutput >::RecomputeGaussianKernel | ( | ) | [protected] |
| virtual void itk::Object::Register | ( | ) | const [virtual, inherited] |
Increase the reference count (mark as used by another object).
Reimplemented from itk::LightObject.
| void itk::Object::RemoveAllObservers | ( | ) | [inherited] |
Remove all observers .
| void itk::Object::RemoveObserver | ( | unsigned long | tag | ) | [inherited] |
Remove the observer with this tag value.
| void itk::Object::SetDebug | ( | bool | debugFlag | ) | const [inherited] |
Set the value of the debug flag. A non-zero value turns debugging on.
| static void itk::Object::SetGlobalWarningDisplay | ( | bool | flag | ) | [static, inherited] |
This is a global flag that controls whether any debug, warning or error messages are displayed.
Referenced by itk::Object::GlobalWarningDisplayOff(), and itk::Object::GlobalWarningDisplayOn().
| virtual void itk::ImageFunction< TInputImage, TOutput, TOutput >::SetInputImage | ( | const InputImageType * | ptr | ) | [virtual, inherited] |
Set the input image.
- Warning:
- this method caches BufferedRegion information. If the BufferedRegion has changed, user must call SetInputImage again to update cached values.
| virtual void itk::DiscreteGradientMagnitudeGaussianImageFunction< TInputImage, TOutput >::SetInputImage | ( | const InputImageType * | ptr | ) | [virtual] |
Set the input image.
- Warning:
- this method caches BufferedRegion information. If the BufferedRegion has changed, user must call SetInputImage again to update cached values.
| virtual void itk::DiscreteGradientMagnitudeGaussianImageFunction< TInputImage, TOutput >::SetInterpolationMode | ( | InterpolationModeType | _arg | ) | [virtual] |
Set/Get the interpolation mode.
| virtual void itk::DiscreteGradientMagnitudeGaussianImageFunction< TInputImage, TOutput >::SetMaximumError | ( | double | _arg | ) | [virtual] |
Set/Get the desired maximum error of the gaussian approximation. Maximum error is the difference between the area under the discrete Gaussian curve and the area under the continuous Gaussian. Maximum error affects the Gaussian operator size. The value is clamped between 0.00001 and 0.99999.
| virtual void itk::DiscreteGradientMagnitudeGaussianImageFunction< TInputImage, TOutput >::SetMaximumKernelWidth | ( | unsigned int | _arg | ) | [virtual] |
Set/Get 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::Object::SetMetaDataDictionary | ( | const MetaDataDictionary & | rhs | ) | [inherited] |
- Returns:
- Set the MetaDataDictionary
| virtual void itk::DiscreteGradientMagnitudeGaussianImageFunction< TInputImage, TOutput >::SetNormalizeAcrossScale | ( | bool | _arg | ) | [virtual] |
Set/Get the flag for calculating scale-space normalized derivatives. Normalized derivatives are obtained multiplying by the scale parameter t.
| virtual void itk::Object::SetReferenceCount | ( | int | ) | [virtual, inherited] |
Sets the reference count (use with care)
Reimplemented from itk::LightObject.
| void itk::DiscreteGradientMagnitudeGaussianImageFunction< TInputImage, TOutput >::SetSigma | ( | const double | sigma | ) | [inline] |
