Research Paper
Core Innovation
This paper introduces LRD-Net, which combines a sequential frequency-guided architecture with a real-centered learning strategy to improve cross-domain face forgery detection. Unlike prior dual-branch models, it efficiently integrates frequency and spatial features without redundancy, achieving state-of-the-art accuracy with significantly fewer parameters and faster processing.
Why It Matters
Face forgery detection is critical for digital security but existing methods struggle with unseen forgery types and require heavy computation. LRD-Net addresses these issues by providing robust detection across domains with minimal resource use, enabling practical deployment in mobile authentication and forensic applications. This improves security workflows by balancing accuracy and efficiency at scale.
