DeepSwap

Detects facial landmarks and geometry in uploaded images using deep learning-based face detection (likely MTCNN or RetinaFace), then applies a generative face-swapping model (possibly a variant of deepfaceLive or similar GAN-based architecture) to seamlessly blend the source face onto the target face while preserving lighting, skin tone, and head orientation. The process involves face alignment, feature extraction, and blending to maintain photorealism without visible artifacts at face boundaries.

Processes video frame-by-frame using the same face detection and GAN-based swapping pipeline as static images, but adds temporal smoothing to prevent flicker and jitter between consecutive frames. The system likely tracks face position and orientation across frames using optical flow or Kalman filtering, then applies consistent face-swap parameters across the sequence to maintain visual coherence. Output is re-encoded into MP4 or WebM format with audio preservation.

Provides an interactive web interface for users to upload or select source and target faces, with real-time preview of detected faces overlaid on the image/video. The UI likely uses canvas-based face bounding box visualization and allows users to manually correct or deselect detected faces if the automatic detection fails. Selection state is maintained in the browser session and passed to the backend processing pipeline.

Implements a credit system where free users receive a limited daily or monthly allowance (e.g., 3-5 image swaps or 1-2 video swaps per day), and paid users unlock higher quotas based on subscription tier. The backend tracks credit consumption per user session, enforces rate limits via IP/account-level throttling, and applies watermarks to free-tier outputs as a visual indicator of tier status. Paid tiers ($9.99-$19.99/month) remove watermarks and increase quotas proportionally.

Automatically embeds a visible watermark (typically a logo or text overlay) on all free-tier outputs at the image encoding stage, serving as both a branding mechanism and a visual indicator of tier status. Watermarks are applied post-processing before final image/video encoding, using either pixel-level overlay (for images) or frame-level compositing (for videos). Paid subscriptions disable this watermark application, providing clean outputs without modification.

Manages asynchronous processing of face-swap requests through a backend job queue (likely using Redis, RabbitMQ, or similar), assigning each request a position in the queue and providing users with estimated wait times based on queue depth and average processing duration. The system scales worker processes based on queue length and provides real-time status updates via WebSocket or polling. Users can monitor progress and receive notifications when processing completes.

When face detection fails (e.g., due to extreme angles, occlusion, or low resolution), the system provides specific feedback to users about why detection failed and suggests corrective actions such as re-uploading a clearer image, adjusting the angle, or removing obstructions. The backend logs detection failures and may offer automatic retry with adjusted detection parameters (e.g., lowering confidence thresholds) without consuming additional credits.

Implements backend checks to detect and prevent face-swapping of sensitive content such as non-consensual intimate imagery, political figures, or minors. The system likely uses image classification models to identify prohibited content categories and may flag suspicious usage patterns (e.g., repeated swaps of the same target face) for manual review. Detected violations result in account suspension or content removal, though the moderation criteria and enforcement are not publicly transparent.

Allows users to export processed face-swaps in multiple formats (JPG, PNG for images; MP4, WebM for videos) with adjustable quality/compression settings. The backend uses FFmpeg or similar encoding libraries to transcode outputs, with quality presets (low/medium/high) that trade file size for visual fidelity. Users can select output format and quality before final export, with estimated file size displayed.

Primarily processes face-swaps on backend servers (cloud-based GPU inference), but may offer optional client-side processing for images using WebGL or WebAssembly to reduce server load and latency. The architecture routes requests to either local browser processing (for simple images) or cloud servers (for videos or complex scenarios), with transparent fallback if client-side processing fails. This hybrid approach balances latency, cost, and reliability.
