REGISTERING INTERFEROMETRIC SAR IMAGES USING MARRHILDRETH ZERO-CROSSINGS
Registration SAR Edge Image Digital
2015/6/1
Leberl (Leberl, 1990) proposed an edge-based algorithm for finding matching pairs of points in SAR images. In this paper, we show that the algorithm can be used to register interferometric SAR images ...
THE CONTRAST RESEARCH OF THE METHODS OF RESTRAINING THE SPECKLE NOISE OF SAR IMAGES
