【摘要】：复杂的海空背景环境中云层、波浪反射、复杂气象条件等会给海天线检测带来困难。针对复杂背景下海天线检测的环境适应性问题,提出了一种基于图像边缘相位编码的海天线检测方法。该算法通过双边滤波原理对图像进行保边滤波处理,以高斯拉普拉斯算子增强边缘响应,配合设计的高斯核方向滤波器完成边缘相位编码的抑噪和增强,然后以相位组分内扫描线的累积响应强度和海天区域内像素强度分布模式差值辨识出最优海天线的位置。实验结果表明,该算法能够有效地检测出不同复杂背景条件下的海天线,具有计算量小和环境适应性强的特点。
[Abstract]:It is difficult to detect sea antenna in complex sea and air background, such as clouds, wave reflection and complex weather conditions. Aiming at the environmental adaptability of sea antenna detection in complex background, a sea antenna detection method based on image edge phase coding is proposed. In this algorithm, the edge preserving filter is applied to the image through the principle of bilateral filtering, and the edge response is enhanced by Gao Si Laplace operator, and the edge phase coding noise suppression and enhancement are accomplished with the designed Gao Si kernel direction filter. Then the position of the optimal sea antenna is identified by the difference between the cumulative response intensity of the scanning line within the phase component and the pixel intensity distribution in the sea and sky region. The experimental results show that the proposed algorithm can effectively detect the sea antennas under different complex background conditions and has the advantages of low computational complexity and strong environmental adaptability.
