Abstract

fetched live from OpenAlex

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.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
