舰船目标海天线提取方法研究

针对反舰红外成像导弹舰船目标的成像特点,提出使用邻域平均和对比度扩展相结合的方法进行预处理以抑制背景、增强目标,进而利用改进的直线拟合法进行海天线的提取。结果表明,该方法能够有效地确定舰船目标红外图像中的海天线区域,保证了目标分割的有效性和实时性。

Research on Locating the Horizontal Region of Ship Target

According to the characteristic of anti-ship inf ra red imaging missile ship target,a new method was proposed,which uses neighborhoo d median combined with contrast stretch to suppress background and enhance targe ts,then uses improved linear fit to locate the horizontal region.The experiment result with ship target infrared image shows that this method can locate precise ly the horizontal region and assures the validity and real-time of image segmen tation.
