Abstract
This paper describes a novel method for modeling the shape and appearance of human faces in three dimensions using a constrained three-dimensional (3-D) active appearance model (AAM). Our algorithm is an extension of the classical two-dimensional (2-D) AAM. The method uses a generic 3-D wireframe model of the face, based on two sets of controls: anatomically motivated muscle actuators to model facial expressions and statistically based anthropometrical controls to model different facial-types. The 3-D anthropometric-muscle-based model (AMBM) of the face allows representing a facial image in terms of a controlled model-parameter set, hence, providing a natural and constrained basis for face segmentation and analysis. The generated face models are consequently simpler and less memory intensive compared to the classical appearance-based models. The proposed method allows for accurate fitting results by constraining solutions to be valid instances of a face model. Extensive image-segmentation experiments have demonstrated the accuracy of the proposed algorithm against the classical AAM.

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
