提出了一种终海出海口冰川崩解锋自动圈定的方法。我们利用Canny边缘检测方法和最短路径优化问题，在Sentinel-1和TerraSAR-X的SAR后向散射图像上找到了产犊前沿位置（CFL）。在格陵兰东北部Zachariae Isstrœm获取的Stripmap图像上检测到CFL，那里存在CFL检索困难的条件。我们将我们的结果与手工描绘的cfl进行比较，发现很好的一致性，与使用的传感器无关。
This paper presents an approach for automatic calving front delineation of marine-terminating outlet glaciers. We utilize a Canny edge detection approach together with a shortest path optimization problem to find calving front locations (CFL) on SAR backscattering images from Sentinel-1 and TerraSAR-X. The CFLs are detected on Stripmap images acquired over Zachariae Isstrœm in Northeast Greenland where difficult conditions for CFL retrieval exist. We compare our results to CFLs that are delineated by hand and find good agreement, independent of the used sensor.
