TOutput operator()(const TInput1 &A, const TInput2 &B) const
~MaximumImageFilter() override=default
The base class for all process objects (source, filters, mappers) in the Insight data processing pipe...
Base class for all process objects that output image data.
bool operator!=(const Maximum &) const
Implements pixel-wise generic operation of two images, or of an image and a constant.

bool operator==(const Maximum &other) const
Functor::Maximum< typename TInputImage1::PixelType, typename TInputImage2::PixelType, typename TOutputImage::PixelType > FunctorType
Implements a pixel-wise operator Max(a,b) between two images.
