关于 Extract Object
在 `image_url` 中的图像里查找 `prompt` 描述的对象,并将其与分割蒙版一起返回到透明背景上。`autocrop` 会将画布裁剪至贴合对象。`remove_background` 会通过移除背景来优化抠图边缘,而不是仅使用分割蒙版。如果没有匹配对象,则返回完整的输入图像。
参数
发送规范名称或原生名称之一,不要同时发送两者。 规范名称
名称类型
默认值允许值
描述
image_url可选
image
类型url · image
默认值https://bria-datasets.s3.amazonaws.com/object-extraction/tools_construction_flatlay.jpg
通过公共 URL、原始 base64 编码图像字节,或类似 data:image/png;base64,... 的 base64 数据 URI 提供的源图像。
prompt可选
类型string
默认值yellow hammer
要处理的对象,使用自然语言描述,例如 'the red car'。
autocrop可选
类型boolean
默认值false
裁剪输出画布以适应提取的对象。
remove_background可选
类型boolean
默认值false
抠图 alpha 优化开关。默认值 False 会跳过显著对象抠图,直接使用 SAM 分割结果中的 alpha,从而加快处理并帮助保留文本、徽标或图形,避免 RMBG 过度裁剪。设置为 True 可使用 RMBG 背景移除来优化 alpha。
必填
规范名称,也可接受
文件参数接受公开的 https:// URL、最大 10 MB 的 data: URI,或上传文件的 file_url。 文件

你的文件,由你选择每个 outputs[].url 都是存储中的副本:可永久保存(按 GB-月付费),也可免费保存 7 天,由账户设置或 ?storage= 决定。
每个模型的结构相同图像、视频和音频均包含 type、url、content_type、width、height 和 duration。output 是模型自身的结果对象。
输出字段
- image
- object {url, content_type, file_name, file_size, width, height}如果提示词未找到匹配对象,则返回完整源图像;否则返回周围带透明区域的 RGBA 结果。
- mask
- object {url, content_type, file_name, file_size, width, height}提取蒙版;未匹配时的回退行为取决于输入:RGBA 图像使用其 alpha 通道,其他所有图像生成纯白蒙版。
