The traditional correlation filter tracking algorithm is easy to track failure in the occlusion
out of view
deformation
background clutter
etc
. Aiming at this problem
a fast-scale support correlation filter tracking algorithm was proposed in this paper. Firstly
the support correlation filter was constructed by loop sample
and the tracking problem was considered as a learning problem of the support correlation filter. Then
the discrete Fourier transform and the iterative optimization strategy were used to solve the learning problem of the support correlation filter
it greatly reduced the complexity of the algorithm. At the same time
the problem of scale estimation was transformed into displacement variation in polar coordinates by log polar transformation
and the adaptive scale of target was realized. Finally
an adaptive template updating strategy was adopted to solve the template drift problem in occlusion. The performance of the proposed algorithm was evaluated by using standard database. The results show that the accuracy of the proposed algorithm is 0.964 and the success rate is 0.892
which are superior to the traditional correlation filtering tracking algorithm. It can better solve the problem of target tracking under the conditions of deformation
