VISUAL ANALYSIS AND PROCESSING OF CLUSTERS STRUCTURES IN MULTIDIMENSIONAL DATASETS
Multidimensional Data Visual Analysis Elastic Maps Cluster Structures
2017/6/19
The article is devoted to problems of visual analysis of clusters structures for a multidimensional datasets. For visual analyzing an approach of elastic maps design [1,2] is applied. This approach is...
Analysis of software requirements to represent urban areas with DEMs and 3D visualization of buildings and structures
DEM (Digital Elevation Models) Visualization of 3D DSM (Digital Surface Modeling)
2016/5/20
In order to have an integrated view of an urban area, it is necessary to show the terrain and the structures on it. There are many established computer programs that can do efficiently either task ind...

While standards for automated access and presentation of cartographic data over the internet are defined, services for automated generalisation and the transfer and storage of the data involved are no...
CLASSIFICATION OF LOCAL STRUCTURES IN AIRBORNE THERMAL VIDEOS FOR VEHICLE DETECTION
Detection of vehicles interest points classification
2015/8/3
In this paper airborne thermal videos are used to detect vehicles. The movement of the camera is estimated from the optical flow using projective planar homographies as transformation model. A three l...
An Original Way of Building a TIN with Complex Urban Structures
TIN, CAD Euler Operators Quad-Edge data structure
2015/6/1
Geographical Information System (GIS) software often models a Digital Terrain Model (DTM) by using triangulations (TINs).
Computer Aided Design (CAD) is then used to model complex city structures an...
