Wavelet Speckle Reduction for SAR Imagery Based on Edge Detection
Image processing Filtering Feature detection Geography Image understanding
2015/11/20
This paper introduces a wavelet transform speckle reduction algorithm for Synthetic Aperture Radar (SAR) imagery based on edge detection. Existing speckle algorithm can efficiently reduce the speckle ...
ROAD NETWORK EXTRACTION FROM SAR IMAGERY SUPPORTED BY CONTEXT INFORMATION
Mapping SAR Object Extraction
2015/6/1
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 im...
