  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by ZJU-REAL on GitHub. Read the source before you install it.

Installation

Install the Image Enhance AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/ZJU-REAL/Easel.git /tmp/Easel
mkdir -p .claude/skills
cp -r /tmp/Easel/skills/openclaw/image-enhance .claude/skills/image-enhance
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Image Enhance in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Image Enhance on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Image Enhance is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

图片增强 / 放大

高质量放大 + 去噪 + 锐化 + 调色,改善偏糊/偏暗/有噪点的图片。走 skills/shared/scripts/img_enhance.py

⚠️ 传统确定性增强,不是 AI 超分——能改善轻中度模糊/噪点,但无法凭空造细节。 要 AI 超分/重绘用 ai-image-gen(图生图)。常规缩放/裁切/压缩/水印见 image-editing

输入

字段必填说明
图片要增强的图片(没给就问)
放大倍数默认 2 倍;1 表示只增强不放大
增强项一键 --auto,或分别指定去噪/锐化/对比/饱和

输出(outputs/主题名/

  • 增强后的图片
  • 报告:原尺寸→新尺寸、执行了哪些增强

执行步骤

脚本路径(相对项目根):skills/shared/scripts/img_enhance.pyenhance -h 看参数)。

bash
# 一键增强 + 2 倍放大(最常用)
python skills/shared/scripts/img_enhance.py enhance -i blurry.jpg \
  -o outputs/主题名/out.jpg --scale 2 --auto

# 噪点多的照片:去噪 + 4 倍 + 强锐化
python skills/shared/scripts/img_enhance.py enhance -i photo.jpg \
  -o outputs/主题名/out.png --scale 4 --denoise --sharpen 1.5

# 只调色不放大(偏暗/发灰的图)
python skills/shared/scripts/img_enhance.py enhance -i img.jpg \
  -o outputs/主题名/out.jpg --scale 1 --auto

调参

  • 还是糊:本工具无法造细节,改用 ai-image-gen 图生图超分。
  • 锐化过头有噪点/白边:降低 --sharpen(默认 auto=1.0)。
  • 颜色过饱和--saturation 1.0 关闭增色,或调低。
  • 噪点被放大:加 --denoise(放大前先去噪)。

规则

  1. 先设定预期:这是"改善"不是"重绘",糊得厉害的图别承诺变高清。
  2. 有噪点务必 --denoise(放大前执行,避免噪点被放大)。
  3. 放大统一用 Lanczos 高质量重采样;倍数别盲目开 4x(文件暴涨且无新细节)。
  4. 产物统一进 outputs/主题名/

参考来源

Lanczos 重采样 + UnsharpMask 锐化 + OpenCV fastNlMeans 去噪 + 自动对比度,是无 GPU 的传统 画质提升组合。真正的超分辨率(Real-ESRGAN 等)需 GPU/模型,此处以 ai-image-gen 图生图替代。

Why use Image Enhance on TypingMind?

Because you install it once and use it with any model. Image Enhance is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Image Enhance in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/ZJU-REAL/Easel/tree/main/skills/openclaw/image-enhance. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Image Enhance?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Image Enhance?

As many as you like. As long as a model supports skills, you can use Image Enhance with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Image Enhance AI skill free?

Yes. It is published on GitHub by ZJU-REAL under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
