【Abstract】 Lightweight single-object tracking algorithm based on Transformer was proposed to address the problems of low accuracy performance of target tracking algorithms in complex contexts. The algorithm adopted online time-series adaptive convolution to extract local features of the target,and at the same time introduced a lightweight global context module to extract global features,which jointly constructed an efficient target model.In order to cope with the problem of loss of target information in the similarity graph refinement,a lightweight feature augmentation module was constructed,which enhanced the model’s ability to express the target without increasing the number of parameters of the overall network,so as to increase the accuracy of the model.Finally,the algorithm added a bounding box refinement module,which can better retain the boundary and scale information of the target and improve the tracking accuracy.The experimental results show that compared with the benchmark algorithm,the tracking accuracy and success rate of this paper’s method are improved by 2.5% and 6.9% on the UAV123 dataset,8.8% and 5.9% on the LaSOT dataset,and 2.4% and 2.4% on the OTB100 dataset,respectively.更多还原
