Abstract

fetched live from OpenAlex

A postprocessing approach that uses both statistical and structural information to eliminate the false minutiae in skeleton fingerprint images is described. The attributes of fingerprint ridges are presented by statistics, and these attributes are used to describe the structure of the false minutiae. The proposed approach analyzes the entire minutia structures, not just in a small window, much like the way humans analyze a fingerprint pattern. To verify the effectiveness of the approach, ten processed images with different shapes were contrasted with rolled fingerprint cards. False minutiae made up 36% of the total minutiae before processing and only about 4% after processing. Moreover, the ridge separation and continuity are good throughout the fingerprint image.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

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.
