Abstract

fetched live from OpenAlex

Modeling the human face and producing realistic facial animation are the challenging tasks for computer animators. On the other hand, with the development of advanced laser-scanning service, it is capable of capturing face with millions of triangles. In the situations where the real-time animation is expected, the problem of how to reduce the size of the dense laser-scanned face data for the animation purpose has been addressed. In this paper, firstly we present an approach that is capable of producing the low polygon approximation model for the dense laser-scanned face while accurately conveying the distinguished features in the original data. We modify the predefined generic model based on the feature points to produce the approximation model. The modification of the generic model involves three steps: Radial Basis Function (RBF) morphing; then loop subdivision step followed by mesh refinement. Secondly, instead of creating new facial animation from scratch, we take advantage of the existing source animation data and use the face motion retargeting method to resample the source motion vectors onto our approximation model. The resulting facial animation is fast and efficient.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
