Abstract
A fuzzy anisotropic diffusion algorithm based on edge detection and noise estimation is proposed for image denoising and edge enhancement. The edginess and noisiness fuzzy membership values are calculated with the edge detector and noise deviation of center pixel from the neighboring average, respectively. The employed edge detector provides more accurate estimation of edges and is less sensitive to noise than the gradient operator in anisotropic diffusion. Taking noise into account ensures that the diffusion process works well regardless of the type of noise degradation, and effectively reduces the number of iterations. We demonstrate how the rather complicated edge detection and noise estimation can be put together through fuzzy inference and embedded into anisotropic diffusion to provide better control on the diffusion processing. Quantitative and qualitative evaluations demonstrate superior performance of the proposed fuzzy approach while processing images with additive and multiplicative noise.

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
