wangtingting, LIU Guodong. Automatic extraction and fast tracking of moving target in TV tracking system[J]. Journal of Image and Graphics, 2010, 15(10): 1515. DOI: 10.11834/jig.20101014.
In order to enable TV tracking system to resist external interference when operating automatically
a second order accuracy scheme is proposed to automatically extract and fast track the moving targets. First
a double frame-difference method is presented to obtain the initial template of the input video image combined with the double gate approach of the quartered images. Then
we track the object effectively according to a trajectory prediction operator and adaptive feature matching technique. In a TV tracking system
the algorithm proposed in this paper has been applied in experiments of low-altitude flying targets tracking
which have achieved good tracking results. The results of the experiments show that the proposed method not only meets the real-time target tracking
but also can effectively improve the accuracy of the target identification.
