#include <itkLaplacianImageFilter.h>
This filter computes the Laplacian of a scalar-valued image. The Laplacian is an isotropic measure of the 2nd spatial derivative of an image. The Laplacian of an image highlights regions of rapid intensity change and is therefore often used for edge detection. Often, the Laplacian is applied to an image that has first been smoothed with a Gaussian filter in order to reduce its sensitivity to noise.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
Reimplemented from itk::Object.

protectedvirtual |
Standard pipeline method. While this class does not implement a ThreadedGenerateData(), its GenerateData() delegates all calculations to an NeighborhoodOperatorImageFilter. Since the NeighborhoodOperatorImageFilter is multithreaded, this filter is multithreaded by default.
Reimplemented from itk::ImageSource< TOutputImage >.

LaplacianImageFilter needs a larger input requested region than the output requested region (larger in the direction of the derivative). As such, LaplacianImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.
