reverse‑SynthID: Open‑Source Tool for Detecting and Removing Google Gemini’s Invisible SynthID Watermark
reverse‑SynthID is an open‑source Python project that uses FFT‑based spectral analysis and multi‑resolution codebooks to detect Google Gemini’s invisible SynthID watermark with about 90% accuracy and to remove it, achieving up to 43 dB PSNR and a 91% drop in phase coherence.
