文字識別

使用ML Kit的文本識別API,您可以使用任何基於拉丁語的語言來識別文本(以及更多基於雲的文本識別)。

文本識別可以自動完成信用卡,收據和名片等繁瑣的數據輸入。使用基於雲的API,您還可以從文檔圖片中提取文本,可用於增加可訪問性或翻譯文檔。應用程序甚至可以跟踪現實世界中的對象,例如通過讀取火車上的數字。

iOS Android

如果您是Flutter開發人員,則可能對FlutterFire感興趣,它包括Firebase ML Vision API的插件。

Professor. He had evidently expected some such call, for

he could hear the opening of the door of our room. He
came at once; as he passed into the room, he asked Mina
