Abstract
We propose a real-time visual hand tracking and posture estimation system to study prehension gestures. This system is based on an original 26 degree-of-freedom model of the hand, for which forward and inverse kinematics formulations have been developed. The hand, wearing a dark glove marked with colored cues, is tracked in real time in the image. The position of the color markers in the image is used to reconstruct the pose of the hand and the postures of the fingers. Occlusion handling is achieved by prediction of finger positions and is validated by testing 3D geometric visibility conditions. Results on real and synthesized image sequences with finger occlusions are presented.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
