Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Add the bone-length prior to the base loss (ablation) | ElePose · Human3.6M | PA-MPJPE: 77.9 -> 48.1 | Helped |
| Add elevation prediction to the base loss and bone-length prior (ablation) | ElePose · Human3.6M | PA-MPJPE: 48.1 -> 45.5 | Helped |
| Add PCA projection to the base loss and bone-length prior (ablation) | ElePose · Human3.6M | PA-MPJPE: 48.1 -> 43.1 | Helped |
| Add elevation prediction to the base loss, bone-length prior, and PCA projection (ablation) | ElePose · Human3.6M | PA-MPJPE: 43.1 -> 36.7 | Helped |
| Add PCA projection to the base loss, bone-length prior, and elevation prediction (ablation) | ElePose · Human3.6M | PA-MPJPE: 45.5 -> 36.7 | Helped |
| Use 22–30 PCA bases rather than a smaller or larger subspace (ablation) | ElePose normalizing flow · Human3.6M | PA-MPJPE: above 100mm | Mixed |
| Learn elevation angles and their dataset distribution rather than using a predefined elevation prior | ElePose · Human3.6M | PA-MPJPE: approximately 15% | Helped |
| Use learned elevation prediction and distribution | ElePose · Human3.6M | MPJPE: more than 22% | Helped |
