关于 Bria Guided Remove Background
从 `image_url` 中主体的默认抠图开始,然后使用可选的自然语言 `prompt` 对其进行调整,例如保留额外对象或仅保留某个对象。保留原始像素并添加 alpha 通道,以 RGBA PNG 格式返回。`autocrop` 会将画布裁剪至贴合保留内容。
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://labs-assets.bria.ai/api-examples/guided-remove-background/yoga_studio_input.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 | null
对默认抠图的可选自然语言调整:使用 'the person with the mat and the plant' 扩大选择范围,使用 'the woman at her desk without the lamp' 排除对象,或使用 'only the chair' 进行限制。空值会选择照片中明显的主体,不作调整。保留的像素保持不变;仅添加新的 alpha 通道。
autocrop可选
类型boolean
默认值false
将输出画布紧密裁剪到保留内容周围。
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
