Individual Tree Segmentation from Side-View LiDAR Point Clouds of Street Trees Using Shadow-Cut
Remote Sensing, 2022 Segmentation of vegetation LiDAR point clouds is an important method for obtaining individual tree structure parameters. The current individual tree segmentation methods are mainly for airborne LiDAR point clouds, which use elevation information to form ...

Individual Tree Crown Segmentation and Classification of 13 Tree Species Using Airborne Hyperspectral Data [PDF]
Remote Sensing, 2018 Knowledge of the distribution of tree species within a forest is key for multiple economic and ecological applications. This information is traditionally acquired through time-consuming and thereby expensive field work. Our study evaluates the suitability of a visible to near-infrared (VNIR) hyperspectral dataset with a spatial resolution of 0.4 m for ...

Structured Pointcloud Segmentation for Individual Mangrove Tree Modeling [PDF]
, 2020 Tree structure parameters of mangrove forests are hard to measure in the field and therefore inventories of this type of forests are impossible to keep up to date. In this article, we tested a structured pointcloud segmentation method for extracting individual mangrove trees.
