SimAug: Learning Robust Representations from Simulation for Trajectory Prediction

1 code implementation ECCV 2020 Junwei Liang, Lu Jiang, Alexander Hauptmann

We approach this problem through the real-data-free setting in which the model is trained only on 3D simulation data and applied out-of-the-box to a wide variety of real cameras.
