RadialGradientCentered3d

Performs a three-dimensional gradient projection with a directional vector defined by a center point.

Access to parameter description

For an introduction: The RadialGradientCentered3d algorithm performs a gradient projection by computing the directional vector from a single given center. For all voxels $P$ in the image, the projection is applied from the same user-defined center $C$.
