Abstract
A physically based approach to the recovery of nonrigid 3-D motion and the tracking of nonrigid objects is presented. The approach makes use of deformable superquadrics, dynamics models that offer global deformation parameters which capture large-scale features and local deformation parameters which capture the details of complex shapes. The equations of motion governing the behavior of the models make them responsive to externally applied forces. The authors extend their prior formulation of these equations to include globally parameterized tapering and bending deformations. They further generalize the formulation to handle physically based point-to-point constraints between models. Such constraints enable one to automatically assemble object models from interconnected deformable superquadric parts. These composite models may be used to track the motions of articulated, flexible objects.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
