复杂海天线区域检测算法研究

Research on complicated sea-sky-line area detection algorithm

分析了红外图像目标特性及背景特性,根据远距离舰船小目标总是出现在海天线附近,在分析海天线特征的基础上,提出了采用最大类间方差法选取灰度阈值检测出海天线的方法,为进一步检测小目标做好了准备.仿真实验结果表明,该方法能够检测出复杂海空背景的海天线.

The features of infrared image target and their background are studied. Since the small target of marine ships in the distance is always seen near the sea-sky-line, the sea-sky-line can be detected by selecting gray threshold based on the maximum variance between classes, making preparation for further detection of small targets. The experimental results show that the method can detect the sea-sky-line from complex sea-sky background.
