Assessment of Road Extraction Performance Using Photo- graphic and Quasi-Photographic SAR Imagery
نویسنده
چکیده
Speckle reduction techniques are applied to SAR imagery to produce images that are almost photographic in appearance ("quasi-photographic imagery"). A road tracking system designed for use with photographic imagery has been used to process this data. The road networks extracted from the quasi-photographic imagery are compared with those produced from optical imagery. It was found that the performance was affected by the SAR resolution. Additionally, urban road networks were better defined when they were parallel to the radar line of sight than when perpendicular to it.

Road Network Extraction from Sar Imagery Supported by Context Information
This paper deals with automatic road extraction from SAR imagery. In general, automatically extracted road networks are not complete, i.e., gaps remain in the erxtracted network. Especially in SAR imagery many objects occlude road sections and cause gaps, due to the side looking geometry of the SAR sensor. In this paper an approach for automatic road extraction is proposed that is optimized for...
متن کاملRoad Extraction from Multi-frequency and Polarimetric Sar Imagery
Automatic extraction of linear topographic objects, such as, roads, rivers, or power lines, is an important topic for topographic mapping. In case of roads, an automatic extraction from Synthetic Aperture Radar (SAR) imagery is rather difficult, due to the speckle effect and the limited spatial resolution in relation to the road width. In this paper we investigate the additional use of multifre...

متن کاملAnalysis of Uncertain Factors in Automatic Extraction of Roads from Sar Imagery
The uncertain factors of automatic extracting roads from the Synthetic Aperture Radar (SAR) imagery have been considered in details in the paper. We consider that the key point of the extraction is the accurate detection of the road points in the image. So, to get the good result, at first, through analyzing the roads features in the SAR image, we got the local model of roads structure. Then ut...

This paper introduces an innovative road network extraction algorithm using synthetic aperture radar (SAR) imagery for improving the accuracy of road extraction. The state-of-the-art approaches, such as fraction extraction and road network optimization, failed to obtain continuous road segments in separate successions, since the optimization could not change the parts ignored by the fraction ex...
