Module Description
Module performs pixel-wise addition of two images. The module makes use of ITK filters for adding the two images. The module provides support for rescaling the input images to perform addition when the size of the inputs differ. However, it does not register the input images with respect to each other. It is therefore the user's responsibility to make sure that the input images are of the same size to obtain meaningful results.
Usage
Load the input volumes. The default setting of the interpolation order should work fine. Its best to use the input volumes of the same size as the module does pixel-wise additions.
Examples, Use Cases & Tutorials
This module can be used for producing intermediate results that can then be plugged as inputs to other filters and modules.
Quick Tour of Features and Use
- "Inputs/Outputs:" This module requires two input volumes, and the specification of an output volume. The module produces the output volume of the same size as the first input volume.
- "Parameters:" The module uses one parameter Interpolation Order. The interpolation order sets the degree of B-spline interpolation to be performed on the second input image for resampling it to the same size as the first input image. The default setting is 1. In general, if the input and output images are of the same size, this parameter can be left at the default setting.
Development
Dependencies
