| 摘 要： | 通过对SAR图像的目标特性分析，提出了一种SAR区域型目标的检测方法。与通常的一些目标检测算法相比，该算法在ROI的提取和目标建模两个方面作了改进，提出了一个新的特征提取算子并引入多尺度的梯度特征作为分类依据。算法应用于真实的SAR图像进行居民区的检测，获得了预期的结果。实验表明，基于多尺度梯度特征的目标检测算法具有良好的性能。

| Abstract: | A SAR regional object detection approach is presented in this paper. There are two key issues in it:extraction of the regions of interest(ROI) and object modeling. In extraction of the ROI,a new edge detector and a grouping segmentation method based on multi-scale gradient features are developed. In object modeling, semantic knowledge is integrated as the object model. The new approach is applied to real SAR images, and the expected results are obtained. It shows that the approach based on multi-scale gradient features has better performance, and regional objects such as residential areas can be detected. |
