摘要
低信杂比下的小目标跟踪问题是目标跟踪领域中的难点。本文在理论分析的基础上提出了用小波多分辨力分析法跟踪低信杂比下的点目标 ,同时讨论了该方法与基于边缘检测的跟踪方法的区别。最后用以天空为背景的视频序列及以海洋为背景的视频序列做了实验研究 ,结果表明本文所提方法能够准确跟踪低信杂比下的点目标。
Small target tracking under low signal-to-clutter ratio is a di fficul t point in target tracking field.The tracking for point target by means of wavel et multi-resolution analysis is proposed on the basis of theoretical analysis i n the paper.The difference between this method and the tracking method based on edge detection is descussed at the same time.Finally the experimental study for the video sequence with sky as background and the video sequence with sea as bac k ground is carried out.The results show that the method proposed in the paper can accurately track point targets under low signal-to-clutter ratio.
