Module performs pixel-wise multiplication of two images. The module automatically handles different resolution of the input images. The module supports input images of any data type.
Load the input volumes(images). The default setting of the parameter Interpolation Setting is 1. For input images of the same size, this setting will work correctly. In general, its best to use input images of the same size for the multiplication operation.
Examples, Use Cases & Tutorials
This module can be used for producing intermediate results that can then be as inputs to other modules. Multiplication can also implicitly serve as a masking operation (when the portions of the image to be masked out are set to 0 in one of the input images). The example result depicted on this page, shows the multiplication of two images (input image 1) and a (input image 2) and the result depicts the input volume contained in the input image 2. Note that the multiple will produce a valid masking operation only when the regions to be masked out are 0. In general, this may not be the case and its best to use the MaskImages module.
Quick Tour of Features and Use
- "Inputs/Outputs:" This module requires two input volumes(images), and the specification of an output volume(image). The module produces an output image of the same size as the first input image.
- "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 re-sampling it to the same size as the first input image. The default setting is 1.
Notes from the Developer(s)
This module depends on the ITK libraries.
