Abstract

fetched live from OpenAlex

Abstract In this paper we present a novel single‐frame image zooming technique which is inspired by fractal‐based image zooming, example‐based zooming, and nonlocal‐means image denoising and combines these techniques in a consistent and improved framework. In Bayesian terms, this example‐based zooming technique targets the minimum mean square error (MMSE) estimate by learning the posterior directly from examples taken from the image itself at a different scale, similar to fractalbased techniques. The examples are weighted according to a scheme introduced by Buades et al. to perform nonlocal‐means image denoising. Finally, various computational issues are addressed and some results of this image zooming method applied to natural images are presented. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

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.
