Abstract: For the traditional problems of template drift and the low efficiency of algorithms in video
image target tracking applications, a new template tracking algorithm based on active drift correction
is proposed. The algorithm incorporates a drift correction term and a target tracking term. By adding a
drift correction term into the traditional affine image alignment algorithms, it improved the traditional
expression of target tracking and also it has solved the template drift problem and increased the
robustness of the algorithm. The results show that the new algorithm has higher operation efficiency
and better robustness.
