摘要: 孪生网络在解决目标跟踪问题时具有较大的速度和精度优势,在跟踪领域得到广泛应用。双孪生网络由独立的语义和外观2个分支组成,每个分支都是一个相似学习的孪生网络,解决了原孪生网络精度不足的问题,但其每个分支独立训练,导致系统速度较低。为此,在双孪生网络的基础上提出一种自适应选择跟踪系统ASTS。在测试过程中,简单帧时自动停止网络向前传播,快速判断目标所在位置,从而提高系统的跟踪速度。复杂帧时2个分支相互协调以准确跟踪目标。在OTB2013/50/100和VOT2017数据集上的实验结果表明,相对于固定的双孪生网络目标跟踪方法,ASTS系统具有更快的速度和更高的跟踪准确率。

Abstract: Siamese network is widely used in the field of target tracking because of its significant advantage in high speed and accuracy.The twin network is composed of two independent branches:semantic branch and appearance branch.Each branch is a twin network with similar learning,which solves the problem of insufficient accuracy of the original twin network.However,each branch is trained independently,which results in the decrease of system speed.To address this problem,this paper proposes ASTS,an adaptive selective system based on twofold siamese network.In the testing process,the network automatically stops propagating forward at the simple frame and rapidly judge the position of the target,so as to improve the tracking speed of the system.In the case of complex frames,the two branches coordinate with each other to track the target accurately.Experimental results on the OTB2013/50/100 and VOT2017 datasets show that compared with the fixed twofold siamese network object tracking method,the ASTS system has faster speed and higher tracking accuracy.
