海洋遥感图像舰船尾迹检测研究

The study of ship wake trace detection of ocean remote sensing image

针对传统小波变换的不足,提出利用方向小波进行遥感图像舰船尾迹检测算法。在理论分析的基础上,对模拟船舶尾迹进行不同方向的尾迹区分,方向性明显。最后通过传统小波变换和方向小波变换对比的仿真实验验证,本文所采用的算法更加接近真实的尾迹,且尾迹平滑、清晰,能够体现尾迹的纹理和方向。

In this paper,because of the deficiency of traditional wavelet transform,Proposed a algorithm that using Direction wavelet transform to detect remote sensing image ship wake. Based on the theoretical analysis,Distinguish different directions of Simulation ship wakes. Finally,traditional wavelet transform and directional wavelet transform comparative simulation results showed the algorithm used in this paper was more close to the real trail,and the trail smooth,clear,able to reflect the texture and direction wake.
