摘　　要：提出了基于时域信息与显著性信息融合的地面运动目标检测算法。首先利用时域信息快速提取运动目标,然后在预选目标的扩展区域内利用显著性检测目标,最后将时域检测结果与显著性检测结果相融合以最终检测到运动目标。基于DSP实现了基于航拍视频图像的地面目标检测算法。实验结果表明:本文算法能有效地提高航拍视频图像中地面目标检测的准确性与鲁棒性,同时不会显著增加检测算法的运行时间。A ground moving target detection method based on the fusion of time domain information and saliency information is proposed. Moving target is firstly extracted with time-domain information. Then saliency is used to detect target in the extended region of preseleeted target. Finally the time domain detection result and the saliency detection result are combined to finally detect the moving target. The ground target detection method based on aerial video images is implemented based on DSP. The experimental results show that the proposed method can effectively improves the accuracy and robustness of ground target detection in aerial video images without significantly increasing the running time of the detection algorithm.
