图片增强 / 放大 / 变清晰：高质量放大（Lanczos 2x/4x）+ 去噪 + 锐化 + 自动对比度/饱和度，改善偏糊、偏暗、噪点多的图片。当用户说 图片放大、图片变清晰、提高清晰度、图片增强、去噪点、锐化、图片太糊了、放大到高清、提升画质、优化图片、图片调亮调色 时使用。基于 shared/scripts/img_enhance.py（Pillow+OpenCV）。注意：这是传统增强非 AI 超分，凭空生成细节请用 ai-image-gen 图生图。与 image-editing 区别：那个做缩放/裁切/水印等常规操作，本 SKILL 专做画质提升。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 | 是 | 要增强的图片（没给就问） | | 放大倍数 | 否 | 默认 2 倍；1 表示只增强不放大 | | 增强项 | 否 | 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.py`（`enhance -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）。 …

How to install
mdr add zju-real/easel/image-enhance@sha256:b46c6e6a5e7c8108The line at the top of this page pins the label git:20261012.0d53744, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
