L · 03 — Before & after
Drag the cursor and inspect each pair.
Four real cases: the Gemini watermark on the left, the clean version returned by the local remover on the right.
Drag the handle or use ← → arrow keys to reveal the result.
L · 04 — Algorithm
The algorithm uses reverse alpha blending to recover the canvas.
Ported from the open-source GargantuaX/gemini-watermark-remover project: no generative inpainting, just calibrated alpha maps, local search and validation. It works best when the mark matches Gemini's visible watermark pattern.

P · 0148/96 px Catalog and initial anchor
We match the image size against Gemini's known output catalog and choose the expected 48px or 96px mark with its margins.
- 02
P · 02NCC + Sobel Local template search
If the fixed position is not enough, the engine scans around the anchor using spatial and edge correlation to confirm the template.
- 03
P · 03Reverse alpha Reverse alpha blending
With the calibrated alpha map, each RGB channel solves original = (watermarked - alpha * white) / (1 - alpha).
- 04
P · 04Up to 4 passes Validation and cleanup
Residual signal is measured, then gain tuning, multi-pass removal and subpixel cleanup run only when validation accepts the improvement.
