T-S tracking algorithm based on context auxiliary feature
Occlusion and objects with the same appearance as the target (known as distractors) are extremely challenging in the tracking domain
and distractors appearing around the target during occlusion tend to cause tracking distractors. To resolve this problem
improving the tracking performance under conditions of serious occlusions and distractor by exploiting the context auxiliary feature was proposed. First
the context strength feature and distractors around the target were detected. Second
a dynamic model that can describe the movements of context strength feature and target well and the constraint of distractor were built. Finally
the dynamic model of context strength feature and target were described in particle filter
and the T-S tracking algorithm was proposed. Using a challenging test video from the SPEVI and OTB100 datasets
the proposed algorithm was compared with other six highly ranked tracking algorithms. Two types of evaluation were adopted during testing. The experimental results demonstrate that the error pixel is 24 pixel and 8 pixel when T-S algorithm tracking multifaces and infrared car from SPEVI datasheet
when tracking eight testing videos from OTB100 dataset
the success rate of T-S algorithm is 0.51 when overlap threshold is 0.5 and surpass other compared algorithm. Our proposed T-S algorithm performs well when tracking targets under conditions of serious occlusions and distractors.
