Abstract

fetched live from OpenAlex

Facial texture updating and compression are crucial in achieving realistic facial animation for low-bit rate coding. We present an efficient way to update and encode facial textures in model-based coding. Differing from traditional methods which update the entire facial texture, we propose a partial texture updating method for realistic facial expression synthesis with facial wrinkles. Experiments on video sequences demonstrate the advantage of the proposed algorithm in keeping transmission cost low while producing realistic expressions.

Full frame distilled prediction

Teacher imitation

Not 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.
