Abstract
The fingerprint is a valuable tool for both forensic analysis and community security.Stateof-the-art fingerprint classification methods tend to ignore image quality enhancement as well as use high-dimension feature sets resulting in unnecessary computational complexities.To address these issues, this study proposes an efficient fingerprint classification method that combines Histogram of Oriented Gradient (HOG) and Gabor Filter features with Random Forest (RF) and Na ve Bayes (NA VE) classifiers.It sequentially preprocesses the input with a series of receiving functions that enhance the image, such as grayscale, morphological, and binary.The method's performance was evaluated on the SOCOFing dataset, and 99% classification accuracy was demonstrated using the Gabor-Na ve approach, surpassing some sophisticated techniques in terms of accuracy and computational efficiency.This work contributes to the field by addressing gaps in image enhancement and feature dimensionality, offering a robust solution for authenticating and distinguishing altered fingerprints.Future research could build on this by examining different classifiers for additional optimization and testing the methodology on a variety of datasets.

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 it
