Subtract VOI Background
Image Types
The algorithm is applicable for any 2D, 3D, 4D, color and grayscale images. If the new image exceeds the range that can be stored in an image of that type, the data is either clipped and stored in the original image (Clip mode). Or a new image of a type (int, float...) that can store the range of new data is generated (Promote Image Type mode).
For color images, the dialog box currently disables promotion for color because MIPAV cannot handle negative color values.
Applying the algorithm
To apply the Subtract VOI Background algorithm do the following:
