Object-based Classification of an Urban Area through a Combination of Aerial Image and Airborne Lidar Data
This paper studies the effect of airborne elevation information on the classification of an aerial image in an urban area. In an urban area, it is difficult to classify buildings relying solely on the spectral information obtained from aerial images because urban buildings possess a variety of roof colors. Therefore, combining Lidar data with aerial images overcomes the difficulties encountered...
متن کاملForest Height Mapping Based on Lidar and Sar Data
Researches have shown that 3D vegetation structure exerts a strong influence on radiation transmission and changes radiation and energy balance at the land surface. Vegetation spatial structure including plant height, biomass, vertical and horizontal heterogeneity, is an important factor influencing the exchanges of matter and energy between the landscape and atmosphere, and the biodiversity of...
متن کاملObject-based approach for mapping complex forest structure phases using LiDAR data
Managed forests are important components of the landscape comprising different stand structural phases (stand initiation, stem exclusion and understorey re-initiation) and delivering important ecosystem functions such as timber production and biodiversity. This paper focuses on the development of a classification method for determining structural phases for conifers and broadleaves using LiDAR ...

15 صفحه اولMultispectral Image Analysis Using Random Forest
Classical methods for classification of pixels in multispectral images include supervised classifiers such as the maximum-likelihood classifier, neural network classifiers, fuzzy neural networks, support vector machines, and decision trees. Recently, there has been an increase of interest in ensemble learning – a method that generates many classifiers and aggregates their results. Breiman propo...
