| 摘 要： | 针对低信噪比序列图像中微弱点状运动目标检测,提出了一种基于最大值投影构造组合帧图像与帧序号图像的检测算法,给出了算法的计算步骤。用建立的检测率和虚警率的分析模型,讨论了检测率、虚警率、信噪比、构造组合帧的图像帧数间的关系。仿真结果表明,通过合理选择组合帧数,该算法可有效检测出低信噪比条件下图像序列中的运动点目标和交叉运动的多点目标。 |
| 关 键 词： | 微弱点目标 最大值投影 组合帧 帧序号图 低信噪比 |

| Abstract: | Aimed at large information and difficulty for real-time disposal involved in the detection of dim point moving target in image sequence with low signal noise ratio,a new point target detection algorithm which was based on constructing combined-image and sequence-image was put forward in this paper.The computation step of the algorithm was given.The relationship among detection rate,failed alarm rate,signal noise ratio and project frame was analyzed based on the models of detection rate and failed alarm rate.The simulation results showed that this algorithm could detect the moving point target in the sequence-image and point targets moving across under low signal noise ratio by choosing combined frames reasonably. |
| Keywords: | Dim point target Maximum project Combined-image Sequence-image Low signal noise ratio |
