How It Works
- Sample frames — extracts ~60 frames and computes a mean frame where the static watermark becomes clearly visible
- Detect watermark — scans all four corners using edge density and temporal stability to find the "AI生成" badge
- Build mask — uses Canny edge detection to trace only the watermark text strokes
- Inpaint — removes the watermark from every frame using TELEA inpainting
- Reassemble — encodes all clean frames back into a video with the original audio
