Embodiment Construction
[0044] The present invention will now be further described in conjunction with the embodiments and accompanying drawings:
[0045] Based on the determination of the target position in the first frame, the present invention firstly obtains several target templates by sampling near the initial frame target, and constructs a dictionary for sparse representation. Then, candidate target sampling is performed by particle filtering guided by the particle swarm optimization algorithm. Then the candidate target is sparsely represented, and the representation coefficient is obtained by solving. Finally, the optimal candidate target is obtained as the tracking result. The specific steps are as follows, and the process can refer to the accompanying drawings.
[0046] 1) Read the first frame of image data and the parameters [x, y, w, h] of the target in the first frame of image, where x, y represent the center position of the target, and w, h represent the width and height of the target....
