Abstract

fetched live from OpenAlex

Muscle based face image synthesis is one of the most realistic approaches to realizing life-like agents in a computer. A facial muscle model is composed of facial tissue elements and muscles. In this model, forces are calculated effecting facial tissue elements by contraction of each muscle strength, so the combination of each muscle parameter decides a specific facial expression. Each muscle parameter is decided based on a trial and error procedure comparing the sample photograph and generated image using our Muscle-Editor to generate a specific face image. We propose a strategy of automatic estimation of facial muscle parameters from 2D marker movements using a neural network. We can also carry out 3D motion estimation from 2D point or flow information in a captured image under restriction of a physics based face model.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
