摘　　要：海天线在远距离舰船目标检测中具有重要参考价值。目前,主要的海天线检测算法有直线拟合法、基于加权信息熵、Hough直线检测等,这些算法不同程度地存在运算量较大、应用场合受限等缺点。文中通过研究Seam Carving原理,将该原理运用到图像中最高能量线的检测,通过计算图像中各点的梯度幅值,采用动态规划技术搜索最高能量线,实现了海天线的检测。实验结果表明,该算法不仅具有较高的检测率,同时具有适用范围广、运算量小、实时性强等特点。Sea-sky-line is important reference information for long-range ship detection. At present, the sea-sky-line detection algorithms, such as liner fitting algorithm, weighted information entropy and Hough line detection methods all need large amount of computation to detect the sea-sky-line. A novel sea-sky-line detection method based on Seam Carving was first proposed in this article. Firstly, the gradient amplitude image was calculated, and then dynamic programming searching for the highest energy line was used to extract the sea-sky-line. The experimental results show that the proposed algorithm have the characteristics of high detection accuracy, wide range of applications, low computational complexity and strong real-time.
