Improved SRDCF object tracking via the Best-Buddies Similarity
Aiming at the failure of tracking via spatially regularized discriminant correlation filter (SRDCF) algorithm caused by occlusion
scale change and deformation
an improved SRDCF algorithm based on Best-Buddies Similarity was proposed. Firstly
the proposed algorithm based on SRDCF
locating target and estimating scale in the process of object tracking were complemented by using bi-level search strategy. Secondly
a novel robust template matching technique was used to estimate the candidate object position by integrating the spatial weights
the correlation filter score and the Best-Buddies Similarity score
thus the problem of target relocation in the occlusion was resolved. Finally
the adaptive template updating strategy was employed to mitigate the template drift problem in the case of occlusion. The performance of the proposed algorithm was evaluated on OTB-2013 datasets and was compared with 34 popular algorithms. The results show that the accuracy and the success rate of the proposed algorithm are 0.853 and 0.648
which are 1.79% and 3.51% higher than the traditional SRDCF algorithm
respectively. The proposed algorithm can deal with the matter of occlusion
