Hi, I’m interested in making overlays of two or more 2D images in VTK (e.g., two MRIs taken multiple years apart). There appear to be two ways of doing this in VTK:
- via vtkImageBlend (https://itk.org/Wiki/VTK/Examples/Cxx/Images/CombineImages)
- via vtkImageStack (https://vtk.org/Wiki/VTK/Examples/Cxx/Images/ImageStack)
Can anyone tell me what the pros/cons of the two methods are?
thank you in advance for your assistance,
