Abstract

fetched live from OpenAlex

In earlier work, Yang et al. proposed a highly-effective technique for generating triangle-mesh models of digital images, known as the error diffusion (ED) method. In this paper, we propose a modified version of the ED method that better exploits triangulation connectivity. Through experimental results, our proposed method is shown to generate image approximations of substantially higher quality than those obtained with the ED scheme, by an average margin of about 3 decibels in terms of the peak-signal-to-noise ratio. Moreover, this improvement in quality comes at a relatively modest computational cost, with the proposed method typically requiring only a few seconds of computation time.

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.
