Detailed Description

ImageViz SoRadialGradientLabelProcessing3d engine

The SoRadialGradientLabelProcessing3d engine performs a projected gradient computing the directional vector.

For an introduction, see:

In the continuous 3-D case, for a given pixel $x$ and knowing the gradient $Gx$, $Gy$ and $Gz$, the projected gradient of an image $I(x)$ is defined along the unitary vector $U(u,v,w)$, as :

\[G_p=Gx\times u + Gy\times v + Gz\times w, ~with~ U(u,v,w)=\frac{\overrightarrow{x-p} }{\left \| x-p \right \|}\]

The SoRadialGradientLabelProcessing3d engine performs a projected gradient computing the directional vector from all centers of the objects in the image label. For a pixel $x$ in the image, the center $p$ taken into account is the center of the closest object label.
