vtkImageHybridMedian2D is a median filter that preserves thin lines and corners. It operates on a 5x5 pixel neighborhood. It computes two values initially: the median of the + neighbors and the median of the x neighbors. It the computes the median of these two values plus the center pixel. This result of this second median is the output pixel value.

Member Function Documentation

vtkImageHybridMedian2D* vtkImageHybridMedian2D::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkImageSpatialFilter.

virtual const char* vtkImageHybridMedian2D::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageSpatialFilter.

int vtkImageHybridMedian2D::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageSpatialFilter.

virtual int vtkImageHybridMedian2D::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageSpatialFilter.

vtkImageHybridMedian2D* vtkImageHybridMedian2D::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageSpatialFilter.

void vtkImageHybridMedian2D::ThreadedExecute (  vtkImageData *    inData, vtkImageData *    outData, int    outExt[6], int    id )  [protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method. Reimplemented from vtkImageToImageFilter.

float vtkImageHybridMedian2D::ComputeMedian (  float *    array, int    size )  [protected]
