we first propose an improved local edge detector to detect road elements from sar images. by introducing prior information of road network, we can organize the local line fragment into useful line structure with directional potential function.

首先利用一种改进的SAR图像局部线特征检测算子获得公路段基元，然后引入关于公路特征的先验知识，利用方向势能函数将局部线特征组织成较大线性结构。

The successful application of the wavelet analysis in edge detector, image fusion, image decomposition is emphasized.

重点论述了小波分析在图像边缘检测, 图像融和, 图像消噪中的应用.

In addition, DSC antinoise edge detector ( DSCANED ) design into thick multi-scaling edge detector.

此外, DSC抗噪边缘探测器 ( DSCANED ) 设计成粗尺度边缘检测器.

The Canny edge detector can find the absolute majority of object contours in an image, but it misses some obvious edges, which causes gaps in the contour.

Canny算子可以检测到物体轮廓的绝大部分信息，但是仍然会漏检一些明显的边界，导致轮廓的不连续。

Because the classic edge detector can't be applied to SAR image directly, the RoA algorithm adapting to SAR image is analyzed.
