Abstract

fetched live from OpenAlex

This paper proposes a method to integrate motion and region information into a recursive temporal noise reduction filter for video signals. We also propose an artifact-robust motion detection algorithm suitable for noise reduction. It is based on local low-pass and maximum filters and on noise-adaptive global gray-level stabilization. Region information is obtained from difference frames resulting from the proposed motion detection. The detected motion and regions are then integrated to compute the temporal filter coefficients that reduce both noise and motion blur. Simulation results show that the proposed method increases the performance of recursive temporal filtering and achieves an average gain of 3.6 dB.

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.
