This is an adaptation of the code develop by Lafarge & Pateiro-Lopez (2017) based on Edelsbrunner & Mucke (1994) for the quick extraction of the tree trunk volume. Therefore, if you use this code we kindly suggest to cite these documents in your research.
A numeric
vector with the estimated trunk volume.
