EPPA vs OpenPose Validation Plan

Date: 2026-05-05

Inputs Collected

• Sent material to Cristina: sources/gmail/sent-to-cristina/
• Local bibliography: sources/local/bibliografia-eppa-openpose/
• Drive bibliography ZIP: sources/drive/bibliografia-eppa-openpose.zip
• Misplaced generated reports: sources/local/misplaced-walter/

Workstream

1. Inventory every claim in Presentacion-EPPA-vs-OpenPose.pdf and Material-Complementario-8-Puntos.pdf.
2. Build a claim-evidence matrix:
3. claim
4. source document/page
5. required data
6. reproducible validation method
7. status
8. Re-run baseline pose extraction on EPPA patient images where Cristina authorizes use.
9. Compare:
10. variables that are anatomically equivalent
11. variables that can only be approximated
12. variables that are not supported by OpenPose keypoints
13. Produce a corrected report with only validated statements.

Initial Technical Assumptions

• OpenPose can provide body and hand keypoints, but EPPA's clinically defined anatomical markers are not always the same as pose-estimation landmarks.
• Equivalence must be proved variable by variable. Similar visual landmarks are not enough.
• For posturography, calibration/reference-line handling is part of the measurement and cannot be skipped.

Outputs

• docs/claim-evidence-matrix.md
• reproducible scripts/notebooks for extraction and comparison
• corrected EPPA vs OpenPose report
• issue-linked bibliography notes
