TriplClust: An Algorithm for Curve Detection in 3D Point Clouds,
Image Processing On Line, 9 (2019), pp. 26–46.

In this article, we describe an algorithm for detecting and separating 
curves in 3D point clouds without making a priori assumptions about 
their parametric shape. The algorithm is called 'TriplClust' because it 
is based on the idea of clustering point triplets instead of the 
original points. We define a distance measure on point triplets and then 
apply a single-link hierarchical clustering on the triplets. The 
clustering process can be controlled by several parameters, which are 
described in detail, and suggestions for reasonable choices for these 
parameters based on the input data are made. Moreover, we suggest a 
simple criterion for stopping the single link clustering automatically.
