Edge Detection of River in SAR Image Based on Contourlet Modulus Maxima and Improved Mathematical Morphology被引量：5
《Transactions of Nanjing University of Aeronautics and Astronautics》2014年第5期478-483,共6页吴一全 朱丽 郝亚冰 李立 卢文平 
Supported by the CRSRI Open Research Program(CKWV2013225/KY);the Open Project Foundation of Key Laboratory of the Yellow River Sediment of Ministry of Water Resource(2014006);the Open Project Foundation of Key Lab of Port,Waterway and Sedimentation Engineering of the Ministry of Transport;the State Key Lab of Urban Water Resource and Environment(HIT)(ES201409);the Priority Academic Program Development of Jiangsu Higher Education Institution
To cope with the problems that edge detection operators are liable to make the detected edges too blurry for synthetic aperture radar(SAR)images,an edge detection method for detecting river in SAR images is proposed b...
