3D BUILDING CHANGE DETECTION BETWEEN CURRENT VHR IMAGES AND PAST LIDAR DATA
Change detection LiDAR data VHR images DSM Quality Disparity MRF Optimization
2018/6/5
Change detection is an essential step to locate the area where an old model should be updated. With high density and accuracy, LiDAR data is often used to create a 3D city model. However, updating LiD...
Extraction of Main and Secondary Roads in VHR Images Using A Higher-Order Phase Field Model
Road Urban Satellite Segmentation Modelling Variational methods
2015/12/4
This paper addresses the issue of extracting main and secondary road networks in dense urban areas from very high resolution (VHR, ~0.61m) satellite images. The difficulty with secondary roads lies in...
ROBUST DETECTION OF ROAD JUNCTIONS IN VHR IMAGES USING AN IMPROVED RIDGE DETECTOR
GIS object recognition road detection
2015/6/2
In this paper we present a novel technique for automatic detection of road junctions in VHR satellite images. The detection is based
on an initially detected road network using a differential ridge ...
COMPARISON OF UNSUPERVISED VEGETATION CLASSIFICATION METHODS FROM VHR IMAGES AFTER SHADOWS REMOVAL BY INNOVATIVE ALGORITHMS
shadow removal classification VHR images
2015/5/7
The recognition of vegetation by the analysis of very high resolution (VHR) aerial images provides meaningful information about environmental features; nevertheless, VHR images frequently contain sh...
PERFORMANCE EVALUATION OF ROAD AND BUILDING CLASSIFIERS ON VHR IMAGES
Support vector machine mean shift classifier combination very high spatial resolution image
2014/6/12
A method is proposed for building and road detection on VHR multispectral aerial images of dense urban areas. Spatial and spectral features of segmented areas are classified us...
