UTOMATIC EXTRACTION OF TREES FROM AERIAL IMAGES AND SURFACE MODELS
Forestry Urban Extraction Algorithms
2015/5/18
In this paper we present an approach for the automatic extraction of trees and the boundaries of the tree’s crowns. The approach is
based on a multi-scale representation of an orthoimage and a surfa...
USE OF AERIAL IMAGES FOR REGULAR UPDATES OF BUILDINGS IN THE FUNDAMENTAL BASE OF GEOGRAPHIC DATA OF THE CZECH REPUBLIC
Aerial Image Image Matching Point Cloud Digital Surface Model Spectral Classification
2015/4/1
Digital aerial images (DAI) include position, elevation and also spectral information (visible bands and near-infrared band) about the captured area. The aim of this paper is to present the possibilit...
PANTIR - A DUAL CAMERA SETUP FOR PRECISE GEOREFERENCING AND MOSAICING OF THERMAL AERIAL IMAGES
aerial thermal imaging image fusion multispectral
2015/4/1
Research and monitoring in fields like hydrology and agriculture are applications of airborne thermal infrared (TIR) cameras, which suffer from low spatial resolution and low quality lenses. Common gr...

KNOWLEDGE BASED INTERPRETATION OF MOORLAND IN AERIAL IMAGES
Change detection Knowledge representation Model-based processing Monitoring Multi-temporal
2015/2/4
For the interpretation of remote sensing data the traditional methods such as multispectral classification are in many
cases not sufficient. This applies especially to more complex scenes. In order ...
ATOMI – AUTOMATED RECONSTRUCTION OF TOPOGRAPHIC OBJECTS FROM AERIAL IMAGES USING VECTORIZED MAP INFORMATION
Data fusion Mapping Model-based Processing Feature Extraction Edge Matching Object Reconstruction Roads Buildings
2014/12/31
The project ATOMI is a co-operation between the Federal Office of Topography (L+T) and ETH Zurich. The aim of ATOMI is to update vector data of road centerlines and building roof outlines from 1:25,00...
PROBLEMS IN GEOMETRIC MODELLING AND PERCEPTUAL GROUPING OF MAN-MADE OBJECTS IN AERIAL IMAGES
Image understanding Semantics Knowledge representation Object recognition Urban objects
2014/12/31
Structural approaches of pattern recognition are frequently proposed for man-made objects in aerial images. Especially model based methods are considered using geometric, topologic and structural know...
AUTOMATIC BUILDING RECOGNITION FROM DIGITAL AERIAL IMAGES
City models Building reconstruction Feature extraction Data fusion
2014/12/31
Automatic building extraction from large-scale aerial images is at beginning of the way, but after recent developments in related techniques, it can be automated partly and hence can be economized tim...
