SHI Pengfei, GAO Qingwei, LU Yixiang, et al. Scale adaptive tracking algorithm based on kernelized correlation filters[J]. 2021, (6): 145-148. DOI: 10.13873/J.1000-9787(2021)06-0145-04.
Aiming at the problem that kernelized correlation filter(KCF)is unable to handle scale variation in object tracking algorithm
a system for scale estimation is designed.Around the position estimated by a standard KCF
another filter is convolved with the signal sampled around the position.The maxima in output is treated as a suitable scale in new frame.The experimental results on OTB dataset show that it is able to handle scale variation efficiently.
