Abstract

fetched live from OpenAlex

In image denoising, high‐frequency components are more notable to the human eyes than low‐frequency components. While high‐frequency components contain more variations and represent the detailed textures, the reconstructions of these components are much harder and it is a remaining challenge in image denoising. In this study, a novel edge‐preserving image denoising algorithm is proposed, it treats the low‐ and high‐frequency components of the image separately. For restoration of high‐frequency components, a neighbourhood regression method is proposed. An energy minimisation function is developed to combine the low‐ and high‐frequency components into one model. Experiments show that the proposed method outperforms the state‐of‐the‐art methods in peak signal‐to‐noise ratio, edges preservation and visual performance.

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.
