Training Data

The training data is available on huggingface and we provide scripts to download it. Note that the individual sequence link do not cover the whole ground truth data (e.g., scene flow, optical flow, etc.) and do not cover event data. For the access to these ground truth data, please refer to the full link.

• huggingface link (~1.5 TB)
