Detailed Description

template<class TInputImage1, class TInputImage2, class TOutputImage>
class itk::WeightedAddImageFilter< TInputImage1, TInputImage2, TOutputImage >

Computes a weighted sum of two images pixel-wise.

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.

The pixel type of the input 1 image must have a valid defintion of the operator+ with a pixel type of the image 2. This condition is required because internally this filter will perform the operation

        pixel_from_image_1 * alpha +  pixel_from_image_2 * (1.0 - alpha)

Additionally the type resulting from the sum will be cast to the pixel type of the output image.

The total operation over one pixel will be

  output_pixel = static_cast<OutputPixelType>(
      input1_pixel * alpha + input2_pixel * (1-alpha) )

The alpha parameter is set using SetAlpha.

Warning:
No numeric overflow checking is performed in this filter.
