Abstract

fetched live from OpenAlex

The paper describes a facial mesh compression method based on an optimization algorithm to improve the quality of rendered facial animation. The proposed facial mesh compression algorithm removes the center vertex of a hexagon which consists of six triangles and represents that area with four triangles. To find the optimal vertex for removal, an area based distortion measure is employed. Different reshape models are also considered to minimize the distortion between the original and reconstructed mesh. From different reshape models, one optimum shape is selected to represent the original facial mesh. The optimization algorithm chooses one vertex which yields minimum distortion. Experimental results show that the proposed algorithm reduces data by 20% while maintaining the quality of the rendered facial animation.

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.
