摘要
针对海空环境的特点,在提取海天线前进行有效的背景抑制和目标增强处理。在直线拟合法的基础上提出了一种剔除粗大点的改进方法,并利用Matlab对该方法进行了仿真试验。试验结果表明,该方法可以有效地检测出海空背景下的海天线与舰船位置,为目标识别和图像配准奠定了良好的基础。
Sea-sky-line detection can be implemented by effectively suppressing the background and enhancing the target in an image according to the features of sea-sky environment.An improved method for wiping off crass points is proposed on the basis of the linear fitting algorithm.The method is simulated with the Matlab software.The simulation result shows that this improved method can effectively detect the positions of the sea-sky-line and ships against the sea-sky background.It provides a good basis for target recognition and image registration.
