Abstract

fetched live from OpenAlex

Experimental studies have proved that high frequency components have the maximum contribution in silhouette-based gait recognition. The Radon Transform (RT), used in gait analysis for its ability to compute useful directional projections, fails to capture the necessary high frequency content of images. In this paper we present the Differential Radon Transform (DiffRT) - a novel adaptation of the standard RT designed to extract such high frequency information efficiently. The proposed transform is used to extract a set of features from gait silhouettes. We provide both theoretical and experimental evidence that DiffRT can indeed collect the important image information to facilitate gait-based human recognition. Averaged silhouettes from USF database are used for performance evaluation following the gait challenge framework. Our proposed method achieves high recognition accuracy and outperforms several state-of-the-art algorithms.

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.
