A skill for removing the visible Gemini AI watermark from images using reverse alpha blending with a Python CLI tool and pre-captured watermark alpha maps.
Overview
A Claude Code skill that removes the visible Gemini AI watermark from images using a reverse alpha blending algorithm. It provides a Python CLI tool that processes watermarked images with pre-captured watermark alpha maps, producing clean output images without requiring any HTML or server-side components.
Key Features
- Reverse Alpha Blending Algorithm - Uses mathematical reverse alpha blending with pre-captured watermark alpha maps to cleanly remove the bottom-right Gemini watermark
- Simple CLI Interface - Process images with a single command:
python remove_watermark.py <input-image> <output-image> - Multiple Resolution Support - Includes pre-captured watermark alpha maps at both 48px and 96px sizes for different image resolutions
- Format Flexibility - Output format is automatically inferred from the output file extension by Pillow
- Documented Algorithm - Includes a references/algorithm.md file with the mathematical foundation, detection rules, and known limitations
Who is this for?
This skill is designed for users who need to remove the Gemini AI watermark from generated images for clean presentation or further editing. It is particularly useful for content creators and designers who use Gemini for image generation and need watermark-free versions of their outputs.
