| 摘 要： | 针对红外图像中舰船目标的分布特点，通过海天/海岸线检测确定舰船的大致位置，再利用目标的面积特性确定舰船目标的感兴趣区域(Region of Interest, ROI)。采用中值滤波、Canny边缘检测和Hough变换从红外图像中检测出海天/海岸线，并划定出海天/海岸线区域；然后，通过舰船的面积特征确定ROI。通过Vc++编程对算法进行了实现。结果表明, 该方法简单直观、计算量小, 能有效确定近海岸舰船目标的ROI。

| Abstract: | According to the distribution characteristics of ship targets in infrared images, the approximate locations of ships are determined first through sea-sky line/coastline detection and the Regions of Interest (ROIs) of the ship targets are determined by utilizing the area characteristics of the targets. The sea-sky line/coastline is detected by using median filtering, Canny edge detection and Hough transform methods and the sea-sky line/coastline area is delineated. Then, the ROIs are determined according to the area characteristics of the ships. The algorithm is implemented by Vc programming. The results show that this method is simple and intuitive and can be used to determine the ROIs of ship targets near shore effectively. |
