Thank you for sharing your work. I have one question:

1. There are 2 checkpoints for GCN, model_gcn and model_gcnwild. What is the difference between the two? I notice that model_gcn is used for H36M evaluation and model_gcnwild is used for MuPoTs. Is it because H36M and MuPoTs have different keypoints definition?

Thanks for your interest in our work.

The major reason there are two checkpoints for GCN (model_gcn and model_gcnwild) is that model_gcn is trained on H36M training set only, and model_gcnwild is trained on training+testing sets of H36M. A second reason is that model_gcn used unnormalized skeleton and model_gcnwild used normalized skeleton because the normalized skeleton setting is more suitable for wild videos and the unnormalized skeleton works better on H36M dataset.

Thanks for the prompt reply. By normalization, do you mean scaling the average joint-to-pelvis distance to 1?
