Target-Aware Transformer Tracking

Yuhui Zheng, Yan Zhang, Bin Xiao

Abstract: Object tracking is aimed at locating a specific object in the image sequence, such as pedestrians, vehicles, and so on. The existing algorithms based on siamese neural network predict the target through similarity matching. Although these algorithms have achieved satisfactory performance, in the process of similarity calculation between template image and search image, only local information is often concerned, which makes the algorithms difficult to obtain the optimal solution. To deal with the abovementioned problems, we propose a model based on Transformer, named TaTrack. Specifically, we first use the encoders to enhance the features. Then, the dependency between template features and search features is established through the target-aware module. Finally, we utilize the classification regression network to locate the target, and use the classification score to adapt to update the template image. Experiments show that our model can achieve great performance on GOT-10k, LaSOT, and TrackingNet datasets.
