Researchers have developed a new deepfake detection method called Spectra, which analyzes the internal reconstruction dynamics of images using implicit neural representations (INRs). Unlike traditional methods that focus on visual appearance or frequency-domain artifacts, Spectra examines how an image is reconstructed, potentially capturing more intrinsic differences between genuine and synthetic content. This approach combines semantic visual features with artifact cues derived from INR reconstruction, demonstrating improved robustness and generalization across various deepfake benchmarks and even extending to face presentation attack detection.
