抽象的。在港口监控中，基于卫星视频的监控因其监控范围广，是对地面监控系统的宝贵补充。因此，基于卫星视频的船舶自动检测与跟踪是一个重要的研究领域。但由于船舶尺寸小、无纹理，加上海噪声的干扰，这也是一个具有挑战性的课题。提出了一种利用卫星视频自动检测和跟踪不同尺寸移动船舶的方法。首先，实现两帧之间的运动补偿。然后，将多尺度差分图像的显着图组合起来创建动态多尺度显着图（DMSM），更适合不同尺寸船舶的检测。第三，从DMSM中分割出候选运动区域，根据周围对比度消除误报后可以检测到移动的船舶。第四，利用质心距离、面积比、与移动船舶的直方图距离等重要元素进行船舶匹配。最后利用每三个相邻帧中的中间帧实现船舶关联和跟踪。卫星序列上的实验结果表明，该方法能够有效地检测和跟踪船舶并获得目标轨迹，与其他经典目标跟踪方法相比，在定义的查全率和精度方面均优于其他方法。
Abstract. In port surveillance, monitoring based on satellite video is a valuable supplement to a ground monitoring system because of its wide monitoring range. Therefore, automatic ship detection and tracking based on satellite video is an important research field. However, because of the small size of ships without texture and the interference of sea noise, it is also a challenging subject. An approach of automatic detection and tracking moving ships of different sizes using satellite video is presented. First, motion compensation between two frames is realized. Then, saliency maps of multiscale differential image are combined to create dynamic multiscale saliency map (DMSM), which is more suitable for the detection of ships of different sizes. Third, candidate motion regions are segmented from DMSM, and moving ships can be detected after the false alarms are removed based on the surrounding contrast. Fourth, important elements such as centroid distance, area ratio, and histogram distance from moving ships are used to perform ship matching. Finally, ship association and tracking are realized by using the intermediate frame in every three adjacent frames. Experimental results on satellite sequences indicate that our method can effectively detect and track ships and obtain the target track, which is superior in terms of the defined recall and precision compared with other classical target tracking methods.
