Channel Positive and Negative Feedback Network for Target Tracking

Blog Article

Aiming at alleviate the detrimental effect of similar object interferences and target state changes in SiamRPN tracker, a Channel Positive and Negative Feedback Network (CPFN) is proposed, in which the Gaussian score map is generated by the feature channels selected by a Gaussian kernel, and the map is combined with the classification branches equi jec 7 of SiamRPN.In this way, the feature channels are divided into positive feedback channels and interference channels, and these feature channels are effectively utilized.In addition, a channel weight update strategy is proposed to enhance the robustness wonderstruck enchanted of the tracker and avoid template pollution caused by inadequate template update.Extensive experiments on tracking benchmarks including VOT2016, VOT2018, VOT2019, OTB100, UAV123, LaSOT and GOT-10k show that the proposed CPFN outperforms the state-of-the-art methods based on small backbone network in terms of accuracy and achieves high-speed tracking.
