Comparison of Individual Tree Crown Detection and Delineation Methods
Efficient forest management increases the demand for detailed, timely information. High spatial resolution remotely sensed imagery provides viable sources and opportunities for automated forest interpretation at an individual tree level. Recent research, which aims at providing tree-based forest inventory measurements, has considered automatic individual tree crown detection and delineation. A ...
متن کاملIndividual Tree Crown Delineation Using Multi-scale Segmentation of Aerial Imagery
With the development of remote sensing techniques, parameters of individual trees for forest inventory can be extracted efficiently from high-resolution remote sensing imagery or LiDAR (light detection and ranging) data rather than using field surveys [1]-[4]. As a prerequisite step, individual tree crown (ITC) delineation from highresolution imagery or LiDAR data is one critical issue in curre...
متن کاملIndividual Tree Crown Delineation from Airborne Laser Scanning for Diseased Larch Forest Stands
Airborne laser scanning (ALS) can be utilised to derive canopy height models (CHMs) for individual tree crown (ITC) delineation. In the case of forest areas subject to defoliation and dieback as a result of disease, increased irregularities across the canopy can add complications to the segmentation of ITCs. Research has yet to address this issue in order to suggest appropriate techniques to ap...
متن کاملForest Species Classification and Tree Crown Delineation Using Quickbird Imagery
Efficient forest management requires detailed knowledge of forest stands, including species information and individual tree parameters. Remote sensing data are increasingly being used to investigate forest classification at both coarse and fine levels. In this paper, we first examined the capability of QuickBird multispectral imagery for species level forest classification using eCognition soft...
متن کاملImpact of Tree-Oriented Growth Order in Marker-Controlled Region Growing for Individual Tree Crown Delineation Using Airborne Laser Scanner (ALS) Data
Region growing is frequently applied in automated individual tree crown delineation (ITCD) studies. Researchers have developed various rules for initial seed selection and stop criteria when applying the algorithm. However, research has rarely focused on the impact of tree-oriented growth order. This study implemented a marker-controlled region growing (MCRG) algorithm that considers homogeneit...
