template<class TInputImage1, class TInputImage2 = TInputImage1, class TOutputImage = TInputImage1>
class itk::SubtractImageFilter< TInputImage1, TInputImage2, TOutputImage >
Pixel-wise subtraction of two images.
Subtract each pixel from image2 from its corresponding pixel in image1:
Output = Input1 - Input2.
This is done using
This class is templated over the types of the two input images and the type of the output image. Numeric conversions (castings) are done by the C++ defaults.
Additionally, a constant can be subtracted from every pixel in an image using:
- Note
- The result of AddImageFilter with a negative constant is not necessarily the same as SubtractImageFilter. This would be the case when the PixelType defines an operator-() that is not the inverse of operator+()

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.
