Deep Residual Injection for Full-Spectrum Forensic Signal Perception in Multimodal Large Language Models
arXiv:2606.15880v1 Announce Type: cross Abstract: Multimodal large language models (MLLMs) have been increasingly adopted in forensics for their robust semantic understanding. As AI-generated images become realistic, semantic-level inconsistencies alone are often insufficient for reliable detection. This motivates a critical question: whether MLLMs can achieve full-spectrum forensic signal perception, i.e., capturing low-level generator artifacts without sacrificing pre-trained semantic knowledge. We further perform a layer-wise analysis of forensic signal perception in MLLMs, showing that sem
The rapid advancement and propagation of AI-generated content (images, video, text) necessitates more sophisticated detection methods, as basic semantic inconsistencies are no longer sufficient.
Reliable detection of AI-generated content is crucial for maintaining trust in digital information, managing misinformation, and ensuring the integrity of forensic evidence.
MLLMs are evolving to not only understand semantic content but also to perceive low-level forensic signals, indicating a more robust and granular approach to AI content detection.
