Doubao Watermark Remover

Dependencies

Python 3.9+
Pillow (install with pip install -r requirements.txt)

Quick start

Install dependencies in the scripts folder:
- cd doubao-watermark-remover/scripts && pip install -r requirements.txt
Run the CLI:
- python remove_watermark.py <input-image> <output-image>

CLI usage

Parameters:
- input-image: path to the Doubao watermarked image
- output-image: path for the cleaned image (format inferred from extension)

Example:

python remove_watermark.py ./in.png ./out.png

What this skill provides

scripts/remove_watermark.py: CLI entry point and core algorithm.
scripts/capture_alpha_map.py: Tool to capture Doubao watermark alpha map.
references/algorithm.md: Math, detection rules, and usage guide.

Workflow

First time: Generate alpha map using capture_alpha_map.py
Use remove_watermark.py for batch processing.

Capturing Alpha Map (First Time Required)

Since Doubao watermark pattern may vary, you need to capture the alpha map first:

Generate a pure black image (0,0,0) and have Doubao add watermark to it
Run the capture tool:
```
python capture_alpha_map.py <black-with-watermark.png> <width> <height>
```
Size options: 140x35 (small images) or 180x40 (large images)
The tool will save the alpha map to assets/ folder

Notes

Doubao watermark "豆包AI生成" appears in the bottom-right corner
Script uses Pillow for image IO and per-pixel edits
Output format is inferred from the output file extension

Install doubao-watermark-remover and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
