基矛海天线提取的红外小目标检测方法
内容简介:通过对海上红外图像进行分析,提出了一种基于海天线提取的红外小目标检测方法。该算法的基本思路是根据所需提取目标的特点,首先选择感兴趣的灰度区域,然后运用Canny算子进行边缘检测,接着对图像进行Hough变换检测海天线,最后对海天线以下且符合目标特征的连通域进行标记从而来确定目标的位置。实验结果表明,该方法能较好地检测出海上红外小目标。
Abstract:Through the analysis of infrared images taken on the sea, a method based on the sea-sky-line extraction is introduced for infrared small target detection. The method includes the following steps. First, the gray area of interest is selected. Second, Canny operator is used to detect the edge. Then, the sea-sky-line is detected by using Hough transformation. At last, connected domains which are below the sea-sky-line and accord with the characteristics of the target are marked in order to get the targets' location. The result of the experiment shows that the algorithm does well in detecting the infrared small targets.
