What it does

Remove Bg is an agent skill from ZJU-REAL/Easel. 图片去背景 / 抠图 / 换背景：用 AI 语义分割把主体从背景抠出，输出透明 PNG，或直接换成纯色（电商白底）/ 新场景背景。无需绿幕。当用户说 去背景、抠图、抠图换背景、去掉背景、透明背景、白底图、换背景、抠人像、抠产品、扣图、KO图、商品白底 时使用。基于 shared/scripts/removebg.py（rembg u2net）。与 green-screen 区别：green-screen 处理绿幕视频，本 SKILL 处理任意图片；与 ecom-details-image 区别：那个出电商视觉方案，本 SKILL 只做抠图。

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: An open-source AI agent for social media — discover trends, create content, publish everywhere, and learn what works across Xiaohongshu, Douyin, Zhihu, Bilibili, and more.🎨一个开源的… The licence is Apache-2.0.

Example prompts

  • “/remove-bg”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. 要透明背景必须输出 .png（jpg 不支持透明，脚本会自动改白底并提示）。
  2. 电商主图用 --bg-color white；换场景用 --bg-image（自动等比覆盖裁切）。
  3. 人像优先 u2net_human_seg，商品/通用用 u2net。
  4. 抠图质量取决于主体与背景对比度；复杂/低对比图无法保证完美。
  5. 产物统一进 outputs/主题名/。

What it can do on your machine

Read from SKILL.md and the folder at commit 278f420. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Remove Bg loads about 512 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 87 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~512

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

图片去背景 / 抠图换背景

用 rembg（AI 语义分割）把主体抠出，输出透明 PNG 或换新背景。无需绿幕。全部走 skills/shared/scripts/remove_bg.py。

绿幕视频抠像见 green-screen；电商视觉方案见 ecom-details-image； 常规缩放/裁切/水印见 image-editing。

前置

首次运行自动下载模型（~4-170MB，视模型而定），需外网代理（脚本读 EASEL_PROXY/http(s)_proxy，未设则直连）。先自检：

bash
python skills/shared/scripts/remove_bg.py check

输入

字段必填说明
图片是要抠图的图片（没给就问）
输出背景否透明（默认）/ 纯色 / 换图片背景
模型否通用 / 人像 / 精细，见下表

输出（outputs/主题名/）

  • 抠好的图片（透明用 .png）
  • 报告：所用模型、背景形态

执行步骤

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

bash
# 透明背景（务必输出 .png）
python skills/shared/scripts/remove_bg.py remove -i product.jpg \
  -o outputs/主题名/cutout.png

# 电商白底主图
python skills/shared/scripts/remove_bg.py remove -i product.jpg \
  -o outputs/主题名/white.jpg --bg-color white

# 换新场景背景
python skills/shared/scripts/remove_bg.py remove -i person.jpg \
  -o outputs/主题名/scene.png --bg-image scene.jpg

# 人像 + 毛发边缘细腻
python skills/shared/scripts/remove_bg.py remove -i portrait.jpg \
  -o outputs/主题名/cut.png --model u2net_human_seg --alpha-matting

模型选择

模型适用
u2net（默认）通用主体
u2netp轻量快速（质量略低）
u2net_human_seg人像专用
isnet-general-use更精细的通用分割
silueta体积小的通用模型

抠不干净/边缘毛糙时：换更精细的模型，或加 --alpha-matting（慢但边缘更好，适合头发/毛绒）。

规则

  1. 要透明背景必须输出 .png（jpg 不支持透明，脚本会自动改白底并提示）。
  2. 电商主图用 --bg-color white；换场景用 --bg-image（自动等比覆盖裁切）。
  3. 人像优先 u2net_human_seg，商品/通用用 u2net。
  4. 抠图质量取决于主体与背景对比度；复杂/低对比图无法保证完美。
  5. 产物统一进 outputs/主题名/。

参考来源

去背景用 rembg（u2net 系列显著性目标检测/分割模型）+ onnxruntime CPU 推理，是无 GPU 抠图的 主流方案。换背景合成用 Pillow alpha_composite。把模型加载、代理注入、背景合成封装成确定性脚本。
