Road Extraction from Sar Image Using an Improved Statistical Algorithm
نویسنده
چکیده
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 operator which calculating the homogenous statistic of locate region is applied to reduce the false alarm and smooth the road edge. Finally, the road linear features are extracted by fusing the results of these two operators, and a phase grouping method is used to combine the road linear features. We apply this algorithm to a RadarSat image to illustrate the accuracy and efficiency, and the performance is satisfied. * Cheng Mingyue. EMail:[email protected] .Tel: 86-21-65981710

Object-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images
As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...
متن کاملRoad Extraction from High-Resolution Airborne SAR using Operator Fusion
Extraction of roads from high-resolution airborne XBand SAR data is described in this paper. The method employs identification of regions of interest, followed by fusion of basic road feature detectors and is complemented by a higher level road model. Identification of regions of interest employs a significance test for the local coefficient of variation. In regions of interest a road feature d...
متن کاملUrban Road Network Extraction from Spaceborne SAR Image
A two-step method is developed for the extraction of road network from spaceborne SAR image: road candidates detection and connection. In the road candidates detection, classification of fused infrared and microwave SAR images effectively reduces the noise in the edge detection, and also well removes possible confusion of no-road objects, i.e. linearly-featured rivers in the edge image. Possibl...

متن کاملAutomatic Extraction of Water in High-resolution Sar Images Based on Multi-scale Level Set Method and Otsu Algorithm
Water extraction has an important significance in flood disaster management and environmental monitoring. Compared to optical sensor, Synthetic aperture radar (SAR), which has the properties of high resolution and all-weather acquisition, has been used for water extraction in this paper. Due to the presence of coherent speckles, which can be modeled as strong, multiplicative noise, water extrac...
