Abstract

fetched live from OpenAlex

This paper presents a novel face alignment method for image sequences that integrates Gabor wavelets with the statistical AAM (Active Appearance Model). First, feature points are characterized using Gabor wavelets and can be individually tracked. A disadvantage of this kind of purely feature-based tracking is that errors accumulate and the feature points loose lock on their corresponding features. To overcome this problem, a face affine transform is used to obtain the initial shape of the AAM model. Finally, the AAM is used to impose global constraints upon the local feature points and to produce an exact alignment. Experimental results demonstrate the ability of the proposed algorithm to accurately align and locate facial features.

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.

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.
