AUTOMATIC FAÇADE SEGMENTATION FOR THERMAL RETROFIT
Faç ade segmentation Laser scanning Texturing Thermal images
2014/4/25
In this paper we present an automated method to derive highly detailed 3D vector models of modern building façades from terrestrial
laser scanning data. The developed procedure can be divided i...
Point cloud segmentation for urban scene classification
Segmentation Classification Point cloud Urban Airborne Filtering
2014/4/22
High density point clouds of urban scenes are used to identify object classes like buildings, vegetation, vehicles, ground, and water. Point cloud segmentation can support classification and further f...
An automatic integrated image segmentation, registration and change detection method for water-body extraction using HSR images and GIS data
Water-body extraction image segmentation registration, change detection GIS
2014/4/22
Automatic water-body extraction from remote sense images is a challenging problem. Using GIS data to update and extract waterbody is an old but active topic. However, automatic registration and change...

MULTI-STAGE APPROACH TO TRAVEL-MODE SEGMENTATION AND CLASSIFICATION OF GPS TRACES
Acquisition Data mining Pattern Recognition Classification GPS/INS Segmentation Mapping
2014/5/8
This paper presents a multi-stage approach toward the robust classification of travel-modes from GPS traces. Due to the fact that
GPS traces are often composed of more than one travel-mode, they are...
