Abstract: SiameseFC has the advantages of fast tracking speed and high accuracy,but it still has some defects in complex scenes,and the tracking mode without updating the template will also cause large errors in the scene that changes rapidly.Therefore,this paper proposes a new tracking method,the dual-template asynchronous update based on SiameseFC.Firstly,both the deep and shallow features are extracted from the VGG-16 network,and two sets of corresponding templates are used respectively,the two sets of templates are updated independently and asynchronously to save computing resources.Then,for the update of the template,the initial template,the template used in the previous tracking,and the template extracted from the tracking result of the previous frame are considered at the same time.And it uses an APCE-based judgment mechanism to dynamically allocate the proportions of the three templatets when updating.This algorithm is superior to mainstream algorithms such as SiamRPN in the benchmark results of OTB100,the success rate and accuracy improve by about 4%~5%,and reaches about 44 fps,which is sufficient to meet real-time tracking requirements.

Key words: SiameseFC, VGG-16, Template update, Dual-template, APCE
