| 摘 要： | 针对红外图像中海天线的特点,提出一种基于图像分割的海天线提取方法.首先通过模板运算对图像进行预处理,以增强海天区域的图像梯度值,然后在竖直方向对图像进行分割,以定位局部海天线,最后用直线拟合法找出海天线位置.实验结果表明,该方法可以快速有效地检测出海天线位置,易于工程应用.

| Abstract: | Through analyzing characteristics of infrared image, this article introduces a sea-sky-line extraction algorithm based on image division. Firstly, the image preprocessing is taken by applying big-sacle filtering to enhance the gray gradient in sea-sky-line area. Secondly, image segmentation in the vertical direction is used to identify local sea-sky-line position. Finally, sea-sky-line position is identified by using straight line fitting algorithm. The experimental result showed that the method can locate sea-sky-line efficiently and correctly and can be used for engineering application. |
