Scramblery is a tool designed to scramble images and videos for scientific, privacy, or artistic purposes. It offers various scrambling techniques, including pixel shuffling and frequency domain manipulation using Fourier transforms. This is a "byproduct" of my research for my master's thesis along with butter2d :-)

- Image Scrambling: Various techniques—including advanced Fourier-based scrambling.
- Video Scrambling: Efficient frame processing via GStreamer's pipeline.
- Batch Processing & Face Detection: Process image directories and optionally target faces.
- Face Detection: Detect facial area and scramble facial area (options for: exclude/include bg).
- Diffeomorphic Scrambling: Smooth, topology-preserving spatial warping based on random DCT flow fields. See acknowledgements.
- Temporal Coherence (Optical Flow): Preserve original motion in scrambled video output using SEA-RAFT optical flow. See acknowledgements.
