關於 Extract Object
在 `image_url` 的影像中尋找 `prompt` 描述的物件,並將其與分割遮罩一同回傳於透明背景上。`autocrop` 會將畫布裁切至貼合物件。`remove_background` 會以背景移除功能細化去背邊緣,而非僅使用分割遮罩。若找不到相符物件,則回傳完整輸入影像。
參數
請傳送標準名稱或原生名稱其中之一,不要同時傳送兩者。 標準名稱
名稱類型
預設值允許值
說明
image_url選填
image
類型url · image
預設值https://bria-datasets.s3.amazonaws.com/object-extraction/tools_construction_flatlay.jpg
透過公開 URL、原始 base64 編碼圖像位元組,或如 data:image/png;base64,... 的 base64 資料 URI 提供的來源圖像。
prompt選填
類型string
預設值yellow hammer
要操作的物件,以一般語言描述,例如 'the red car'。
autocrop選填
類型boolean
預設值false
裁切輸出畫布,使其符合擷取物件的範圍。
remove_background選填
類型boolean
預設值false
去背 alpha 精修開關。預設值 False 會略過顯著物件去背,直接使用 SAM 分割結果中的 alpha,因此處理更快,也有助於保留文字、標誌或圖形,避免 RMBG 過度裁切。設為 True 可使用 RMBG 背景移除功能精修 alpha。
必填
標準名稱,也可使用
檔案參數接受公開的 https:// URL、最大 10 MB 的 data: URI,或上傳檔案的 file_url。 檔案

您的檔案,由您選擇每個 outputs[].url 都是儲存空間中的副本:可永久保留(按 GB-月計費),或免費保留 7 天;可透過帳戶設定或 ?storage= 設定。
所有模型使用相同結構圖片、影片和音訊皆包含 type、url、content_type、width、height 和 duration。output 是模型自己的結果物件。
輸出欄位
- image
- object {url, content_type, file_name, file_size, width, height}當提示詞找不到相符物件時的完整來源圖像;否則會回傳周圍透明的 RGBA 擷取物件結果。
- mask
- object {url, content_type, file_name, file_size, width, height}擷取遮罩;找不到相符物件時的備援行為取決於輸入:RGBA 圖像會提供其 alpha 通道,其他所有圖像則產生全白遮罩。
