// .NAME vtkImageNonMaximumSuppression - Performs non-maximum suppression
// .SECTION Description
// vtkImageNonMaximumSuppression Sets to zero any pixel that is not a peak.
// If a pixel has a neighbor along the vector that has larger magnitude, the
// smaller pixel is set to zero. The filter takes two inputs: a magnitude
// and a vector. Output is magnitude information and is always in doubles.
// Typically this filter is used with vtkImageGradient and
// vtkImageGradientMagnitude as inputs.
