Face detection using information fusion
Bibliographic record
Abstract
The fundamental point of this paper is that the fusion of several simple, somewhat unreliable, and somewhat inefficient frontal face detectors results in an efficient and reliable frontal face detector which, without any training, performs similarly to a state-ofthe- art neural network based face detector trained on 60,000 images. The simple detectors used include a skin detector, symmetry detectors, as well as structural face detectors. On a test set of 30 color images containing frontal faces, the fused face detector had an accuracy of 93% with a RMSE of 4.96 pixels, as compared to an accuracy of 87% and a RMSE of 8.00 pixels for the neural network based face detector. On the Caltech Face Database, the fused face detector had a 90% detection rate which is on par with state-of-the-art face detection methods that utilize extensive prior training, including the neural network approach which achieves a detection rate of 94%.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
