“…Generally, now the main strategy of tracking algorithm is to build a faultless appearance model of the target through generative-based (Zhou et al, 2014;Hare et al, 2016;Ning et al, 2016;Gao et al, 2014;Zhou et al, 2013) or discriminative-based (Chan et al, 2017b(Chan et al, , 2017aZhang et al, 2017Zhang et al, , 2020Zhang et al, , 2015bZhang et al, , 2019Zhang et al, , 2015a methods and to update it effectively in subsequent trajectory estimates. However, since the appearance of the object changes differently in each frame of the image sequence, this not only makes it difficult to build a complete description of the appearance of the target object but also leads to the accumulation of errors in the tracking process.…”
