Skeleton tortuosity

Description

Calculates branch tortuosity of the topological skeleton.

Usage

skelTortuosity(skel, cores = 2)

Arguments

skel	topological skeleton, output of readAmiraSkeleton
cores	number of cores for parallel computation (default=2)

Details

Tortuosity of a segment is the ratio between its length and the linear distance between its starting and ending points. In the topological skeleton, tortuosity is calculated as the ratio between the the branch length and the linear distance between the nodes it connects. Tortuosity ranges from 1 to infinity.

Value

A vector of branch tortuosity, of length equal to the number of branches in the topological skeleton.
