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/remove_bg.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。.
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.

How to install
mdr add zju-real/easel/remove-bg@sha256:6a5d23ee1f2c333eThe 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.
