摘要：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 which requires sub-pixel precision. This precision is achieved by interpolating the discrete values of the metric used for matching, in this algorithm, using cubic B-splines. The interferogram obtained is comparable to that obtained using cross-correlation
