MONITORING THE URBAN TREE COVER FOR URBAN ECOSYSTEM SERVICES – THE CASE OF LEIPZIG, GERMANY
Mapping Urban Tree Cover Urban Ecosystem Functions
2015/5/6
Urban dynamics such as (extreme) growth and shrinkage bring about fundamental challenges for urban land use and related changes. In order to achieve a sustainable urban development, it is crucial to...
A PROBABILISTIC APPROACH TO ROOF EXTRACTION AND RECONSTRUCTION
Modelling Reconstruction Building
2015/3/25
This paper investigates into the model-based reconstruction of complex polyhedral building roofs. A set of 3D line
segments, obtained from multiview correspondence analysis of high resolution colour ...
Tracking of multiple objects from ‘real world’ is one of the most complicated problems in computer vision since the
behaviour/motion of these objects is unpredictable and cannot be assumed. Tracking...
HYBRID MATCHING BASED ON POLYNOMIAL TRANSFORMATION
Polynomial Transformation Model Matching
2015/3/25
A new approach for hybrid matching based on polynomial models is proposed. Polynomial plays a key role in matching process;
while the Efficiency Index measures the accuracy of the matching result. A...
RECONSTRUCTION OF 3D LINEAR PRIMITIVES FROM MULTIPLE VIEWS FOR URBAN AREAS MODELISATION
3D Reconstruction Feature Matching
2015/3/25
In this paper, a new method for reconstruction of 3D segments from multiple images in urban areas environment is presented. Compared
to previous algorithms, this one performs the matching of 2D segme...
DIGITAL TERRAIN MODELS FROM AIRBORNE LASER SCANNER DATA - A GRID BASED APPROACH
airborne laser scanning DTM generation
2015/3/25
Since Airborne laser scanning sensors are operational and the data capture, including the calculation of the exterior orientation by
using GPS and INS, has reached a high level of automation, the fo...
INTEGRATED TECHNIQUES FOR LOW-COST SURVEYING OF URBAN AREAS
Integration Mobile Mapping Systems CCD image
2015/3/25
This paper deals with the purpose of a methodology integrating different surveying techniques to efficiently produce a large-scale
digital mapping of urban areas.
At first, a comparison among method...
IMPROVEMENT OF ROAD CROSSING EXTRACTION AND EXTERNAL EVALUATION OF THE EXTRACTION RESULTS
Road crossing modeling extraction correction evaluation
2015/3/25
The extraction of road crossings is often neglected by systems for automatic road extraction. Frequently, crossings arise as
by-products of the grouping step. This leads to geometrical inaccuracies a...
Recent increase in number of pixels of images acquired by a non-metric digital camera encourages an amateur to utilize it for 3D
measurement. Most of current camera calibration methods are inconveni...
TOWARDS A SEAMLESS ROBUST DIGITAL SURFACE MODEL (DSM)
Multiple image matching DEM/DTM Graph theory
2015/3/24
FIFEDOM (Frequent-Image-Frames Enhanced Digital Ortho-rectified Mapping) is an ongoing, multidisciplinary research project
aiming to provide low-cost, information-rich digital mapping through the dev...
JUNCTION EXTRACTION BY ARTIFICIAL NEURAL NETWORK SYSTEM – JEANS
Artificial Neural Networks Automatic Object Extraction
2015/3/24
The paper presents a road junction operator, which was developed for medium resolution black-and-white
orthoimages. The operator uses a feed-forward neural network applied for a running window to de...
ALGORITHM DEVELOPMENT FOR THE ENHANCEMENT OF PHOTOGRAMMETRIC DIGITAL IMAGES TO IMPROVE DEM GENERATION
Photogrammetry digital images
2015/3/24
In digital photogrammetry applications such as digital elevation model generation (DEM), demanding highly detailed images, it is
often not feasible or sometimes possible to acquire images of such hi...
The filtering of a laser scanner point-cloud to abstract the bald earth has been an ongoing research topic in laser altimetry. To date a
number of filters have been devised for extracting DEMs from l...
OCCLUSION, CLUTTER, AND ILLUMINATION INVARIANT OBJECT RECOGNITION
Computer Vision Real-Time Object Recognition
2015/3/24
An object recognition system for industrial inspection that recognizes objects under similarity transformations in real time is proposed.
It uses novel similarity measures that are inherently robust ...
INVESTIGATION OF THE MPEG-7 HOMOGENEUOS TEXTURE DESCRIPTOR FOR THE AUTOMATIC EXTRACTION OF TREES
Urban Vegetation Automation
2015/3/24
In this paper we describe our recent work on the automatic extraction of trees from high resolution aerial images. In order to be more
independent of color information we have investigated textural ...
