Firstly, we coarsely detect the feature image obtained from subimage blocks, the target regions are identified according to prior knowledge.

该文借助知识理论，提出一种新的基于子图像块的区域分割与边缘检测相结合的目标提取方法。

Using the subimage of an unknown target as feature vector and minimum distance rule for target recognition, experiments on simulated data are done.

对未知目标，以其子像对库矢量的欧氏距离最小为分类准则，进行了识别模拟实验。
