| itk::VectorCentralDifferenceImageFunction< TInputImage, TCoordRep >::VectorCentralDifferenceImageFunction | ( | ) | [protected] |
The UseImageDirection flag determines whether image derivatives are computed with respect to the image grid or with respect to the physical space. When this flag is ON the derivatives are computed with respect to the coordinate system of physical space. The difference is whether we take into account the image Direction or not. The flag ON will take into account the image direction and will result in an extra matrix multiplication compared to the amount of computation performed when the flag is OFF. The default value of this flag is On.
