Temporal Aggregation for Adaptive RGBT Tracking

1 code implementation22 Jan 2022 Zhangyong Tang, Tianyang Xu, Xiao-Jun Wu

Specifically, different from traditional Siamese trackers, which only obtain one search image during the process of picking up template-search image pairs, an extra search sample adjacent to the original one is selected to predict the temporal transformation, resulting in improved robustness of tracking performance. As for multi-modal tracking, constrained to the limited RGBT datasets, the adaptive fusion sub-network is appended to our method at the decision level to reflect the complementary characteristics contained in two modalities.
