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 aredetermined 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.
