| 摘 要： | 提出了一种阈值选取与边缘检测相结合提取红外图像特征的方法。对红外图像进行边缘检测，并选定阈值将其二值化；在二值边缘图像中应用双窗口分别选定目标和要去除的噪声，在各窗口中采用双向扫描提取目标特征。实验结果证明了其良好的性能。

| Abstract: | An algorithm using threshold selection and edge detection to extract target features from infrared image was proposed. Edge detection is operated, and threshold is selected to transform the edge image to a binary image;Choose the target and the noise that will be removed in two windows, then extract target with dual-direction scan in each window. The experimental results prove that the proposed method can achieve satisfactory effects. |

| Keywords: | threshold selection edge detection dual-window dual-direction scan |
