SciFigPlag-Bench - Reuse Localization: leaderboard
SciFigPlag-Bench (2026) reuse localization: box the reused subfigure in both the source and the suspicious figure; a pair counts when both boxes reach IoU of at least 0.5. Accuracy in percent, higher is better.
Metric: Paired localization accuracy (%; both the source-side and the suspicious-side boxes of a reused subfigure must reach IoU of at least 0.5; SciFigPlag-Bench pairs of source and suspicious scientific figures (2,582 plagiarized pairs from documented real cases and taxonomy-guided synthesis, 2,541 visually similar negatives); the same task-specific prompts for every model, temperature 0). Source: arxiv.org. Saturation forecast: Around February 2027. 16 models tracked.
