5 秒自动抠图

5 秒去除人像背景 —— AI 帮你自动抠图,无需注册登录、完全免费!

Remove Image Background 是非常火爆的人像照片(其实也可以去除其他物体,比如沙发…)背景去除工具,只需要上传一张带有人像的照片,它就会帮你自动抠掉背景,整个过程全自动、5秒内完成,而且完全免费,甚至还支持多种语言的 Background Removal API 调用。

效果如下图所示,不到5秒瞬间完成…(该图为本人真实、亲测旅游卫视图片处理效果)

Remove Bg 传送门 Removal API 传送门

另外,再推荐一个国内在线的抠图工具 —— 搞定抠图,功能相比 Remove Bg 稍微逊色,主要不够 AI,很多需要人工确定抠图范围,在访问 Remove Bg 遇到困难的时候(remove.bg 使用了 reCAPTCHA 预防滥用,而 re 的服务器位于 Google,所以你懂得 ..),也可以作为备选使用:
