Synthetic Data Are as Good as the Real for Association Knowledge Learning in Multi-object Tracking

no code implementations30 Jun 2021 Yuchi Liu, Zhongdao Wang, Xiangxin Zhou, Liang Zheng

We show that compared with real data, association knowledge obtained from synthetic data can achieve very similar performance on real-world test sets without domain adaption techniques.
