Abstract
The aim of this study was to develop an automatic procedure to detect
tree stems in cell phone images. If the stems can be detected, the central
projection geometry of the images makes it possible to apply the so called
relascope principle to predict the basal area of stems per hectare. The basal
area is closely correlated with tree biomass. Images were acquired in an
area where detailed tree-wise information is available. The tree stem
delineation methods were based on color and edge information to tackle the
challenges of occlusions and varying illumination conditions. Geolocalised
images can be used as in-situ reference data for remote sensing data
analysis to provide wall-to-wall estimates. (10 refs.)
