基于方向小波的弱尾迹检测

针对遥感图像中的弱尾迹检测,提出了一种基于方向小波变换的尾迹检测新算法,并且比较了方向小波和传统的小波变换在检测尾迹中的不同之处。分析得出方向小波变换更符合图像的方向、纹理特征,因而不仅可以有效检测出图像中的弱尾迹,而且可以检测出某一特定方向上的弱尾迹。仿真结果表明,检测效果十分良好。

Weak Wake Detection Based on Directional Wavelet Transform

For the weak wakes detection in remote sensing image,a new algorithm for wake detection based on directional wavelet translform is proposed,and the difference of wake detectin between traditional and directional wavelet transform is compared. The analysis shows that the directional wavelet transforms can better meet the image direction and texlue characer.It can detect not only the weak wake of images effectively but also the weak wake in a special direction.The simulation shows that the result is good.
