Abstract
A novel object tracking algorithm based on hierarchical convolutional features was proposed in this paper. Firstly, the tracking algorithm uses the hierarchical networks of VGG-Net-19 to extract the hierarchical convolutional features of image, having a greater improvement than using only one layer to do that. Secondly, the algorithm obtains features by using correlation filtering method with weighted fusion, so as to determine the real position of the target according to the characteristics of different layers. The experimental results show that, compared with the current four popular object tracking algorithms, the proposed algorithm achieves better accuracy and success rate, and the results are consistent in OPE (one-pass evaluation), SRE (spatial robustness evaluation) and TRE (temporal robustness evaluation).
