| 摘 要： | 针对红外图像目标边缘的模糊性,为了准确提取目标,提出了基于三次样条插值和灰阶边缘细化的方法,该方法通过对边缘过渡区域及其法线方向信息的处理,使图像边缘精确定位在亚像素级。实验结果表明,该方法能够精确定位目标边缘,优于传统的边缘检测方法。

| Abstract: | In view of the fuzziness in edge of IR image, a method based on three-order spline interpolation and gray level edge thinning is proposed in order to accurately extract targets. The image edge can be located in sub-pixel level by this method through processing the information in edge transition area and normal direction. The experimental results show that the method can accurately locate the target edge and it is better than the traditional edge detection. |
