Road Extraction from SAR Image Using an Improved Statistical Algorithm
Road extraction Feature extraction SAR image Speckle statistics Phase grouping
2015/12/9
An efficient statistical algorithm of automatic extracting road from SAR images is devised in this paper. First, an feature detecting operator is used to find the road candidate. Then another smaller ...
Multipolarimetric SAR image change detection based on multiscale feature-level fusion
Multipolarimetric SAR Change Detection NSCT Fusion
2015/7/27
Many methodologies of change detection have been discussed in the literature, but most of them are tested on only optical images or traditional synthetic-aperture radar (SAR) images. Few studies have ...
PRECISE ORIENTATION OF SPOT PANCHROMATIC IMAGES WITH TIE POINTS TO A SAR IMAGE
Image orientation stereoscopic multisensor SAR SPOT parallax
2015/3/24
The extraction of spatial data from satellite imagery requires that precise sensor models are used to orientate images. This is
particularly important with images acquired by linear sensors, such as...
SAR IMAGE TECHNIQUES FOR MAPPING AREAS OF LANDSLIDES.
Landslides Debris flow RADARSAT InSAR SAR Perspective view
2015/2/4
This paper shows that InSAR perspective view and airborne InSAR images are very useful for geomorphic
characterization of landslide features in high relief terrains. Landslides cause approximately 10...
Double Polarization SAR Image Classification based on Object-Oriented Technology
Synthetic Aperture Radar Image Classification Object-Oriented Pixel-Based DEM
2013/3/5
This paper proposed to use double polarization synthetic aperture radar (SAR) image to classify surface feature, based on DEM. It takes fully use of the polarization information and external informati...
