Abstract

fetched live from OpenAlex

The aim of steganography is to hide huge information in a small media with robustness and invisibility. The main idea of this paper is to utilize a threshold mechanism to embed as much information of the secret image into the cover image as possible. The proposed threshold mechanism is setup especially to fit the human visual system. The experimental results show that the proposed human visual system has improved the quality in terms of perceptibility. On the hiding capacity issue, the proposed method has capability to embed a secret image in a cover image which its size is three times or more than the size of cover image.

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.
