Improve mildly blurry, dark, or noisy images with noise reduction, sharpening, and contrast or saturation adjustments. Export enhanced images at their original size or enlarged two or four times, with a report of applied changes.
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。

⚠️ 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。
| 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 |

# 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
--sharpen（默认 auto=1.0）。--saturation 1.0 关闭增色，或调低。--denoise（放大前先去噪）。--denoise（放大前执行，避免噪点被放大）。outputs/主题名/。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。

Generate images from written descriptions, transform existing images with editing instructions, or create several variations. Choose image dimensions and quantity, then save the results using an OpenAI-compatible service or apimart with your own API key.
Generate background music for short videos, vlogs, and social posts from descriptions of mood, style, and instruments. Download MP3 audio, optionally include sung lyrics, and use shared scripts to trim tracks, adjust loudness, or add music to videos.
Create new videos from written scene descriptions or still images using external AI services. Set the aspect ratio and duration, animate a character image, and request generated audio when the selected model supports it.
Organize generated images, videos, and text in outputs/ by date, platform, and type. Add tags, search filenames and content, produce asset lists and reports, and preview archive moves before applying them to make past work easier to reuse.
Reduce background noise in audio recordings or video soundtracks with three processing levels. Keep the original file, create a cleaned version, and receive a report of the settings used and file details before and after processing.
Edit audio files by trimming sections, converting formats, matching loudness, or extracting sound from videos. You can also join recordings, add fades, and change playback speed while keeping the original pitch.
