Reverse Alpha Blending vs AI inpainting
If your goal is precise Gemini watermark cleanup, method choice matters. Reverse Alpha Blending and AI inpainting look similar at first glance but behave very differently in the repaired area.
Quick comparison
| Factor | Reverse Alpha Blending | AI Inpainting |
|---|---|---|
| Core approach | Inverts blend math | Generates new pixels |
| Edge fidelity | Usually higher on original exports | Can blur near boundaries |
| Texture consistency | Preserves original structure | May hallucinate details |
| Privacy | Can run fully local | Often server-side |
When to use each
Use Reverse Alpha Blending when the watermark pattern and compositing behavior are known, especially on untouched Gemini exports. Use AI inpainting when the marked area is heavily damaged or the original blend assumptions no longer hold.
Practical recommendation
Start with deterministic recovery first. If it fails due to non-standard edits, only then move to generative repair. This gives you better quality control and fewer artifacts in most production use cases.
