Abstract

fetched live from OpenAlex

Traditional median filters perform well in restoring the images corrupted by low density impulse noise, but fail to restore highly corrupted images. Conversely, the advanced adaptive median filters are capable of denoising high density impulse noise but the image details are compromised significantly. In this paper, a new adaptive fuzzy median filter is presented to provide optimum detail preservation along with very high density noise removal. The novelty of this research work comes from two directions. Firstly, we used a triangular fuzzy membership function to determine the level of corruption at each pixel that consequently ensures the replacement of noisy pixels according to the extent of corruption. Secondly, we exploited fully adaptive and automatically adjustable threshold value to provide ease of computation. Experimental results show that the proposed filter outperforms other conventional and advanced filters in terms of both denoising and fine detail preservation of highly corrupted images.

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.
