Abstract

fetched live from OpenAlex

Deepfake technology has already impacted the integrity of news and may grow to hugely destructive political and social force. The realistic and convincing nature of deepfakes poses a threat to the authenticity of information, alarming individuals and organizations. While many studies have explored the issue of deepfakes, the majority of them have focused on swapping entire faces rather than partially manipulating them, which can be more difficult to detect. In this paper, we introduce a high-fidelity partially manipulated face dataset, aiming to fill the gap in the existing deepfake research by providing a comprehensive benchmark for partially manipulated face detection. Our dataset includes a diverse set of partially manipulated faces which is generated from high-quality facial images. Our proposed alignment pipeline ensures that the partially manipulated faces may be realistically integrated into the original images, providing a more challenging evaluation environment for deepfake detection models. Both objective and subjective evaluations of our proposed dataset have shown promising results, indicating its potential to become a significant benchmark for partially manipulated face detection.

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.
