CentroidPathTortuosity3d

Computes the tortuosity of a path formed by the centroids on each plan along the Z axis of a three-dimensional binary image.

Access to parameter description

Tortuosity is the ratio of the length of a curve to the distance between the ends of it along the Z axis. In this algorithm, the distance between the ends of curve is given by the number of planes along the Z axis.

This algorithm first computes the centroid $c(i)$ of each plane $z(i)$ of the image. Then it computes the path length through the centroids $l=\Sigma d(i)$ and then divides it by the height traveled along the Z axis: $H=z(n)-z(0)$ .
