A new method for individual treetop detection with low-resolution aerial laser scanned data

Modeling Earth Systems and Environment
AbstractIn the past decade, the use of three-dimensional forest information from airborne Light Detection and Ranging (LiDAR) has become widespread in forest inventories. Accurate Individual Treetop Detection (ITD) and crown boundary delineation using LiDAR data are critical for obtaining precise inventory metrics. To address this need, we introduced a

TREETOP Study: A Novel Lung Function Technique for the Early Detection of Chronic Obstructive Pulmonary Disease

American Journal of Respiratory and Critical Care Medicine
Abstract INTRODUCTION Chronic obstructive pulmonary disease (COPD) causes major morbidity and mortality worldwide. Diagnosis relies on demonstrating airflow limitation on spirometry, which is insensitive to early changes in the small airways (where disease typically begins).

Unsupervised training for treetop detection with airborne laser scanning data

2012
Numerous methods have been proposed for the detection of single trees in airborne laser scanning (ALS) data. Most of them are highly dependent on the initial settings of the algorithm, as parameters (e.g. smoothing of the digital canopy height model) will affect the overall detection performance, and more particularly the trade-off between omission and

Automated Treetop Detection and Tree Crown Identification Using Discrete-return Lidar Data

Accurate estimates of tree and forest biomass are essential for a wide range of applications. Automated treetop detection and tree crown discrimination using LiDAR data can greatly facilitate forest biomass estimation. Previous work has focused on homogenous or single-species forests, while few studies have focused on mixed forests.
