阿里雲視覺智能開放平臺–人臉識別使用教程

  近期平臺上線了30餘個算法，其中就包括大家比較關心的人臉比對1：N算法，為了更方便大家調用此算法，接下來給大家分享一份代碼樣例，其中包含了如何對接並調用人臉比對1：N，對此算法感興趣的小夥伴千萬不要錯過喲~
步驟
1、服務開通，參考鏈接：阿里雲視覺智能開放平臺使用簡明教程

2、目前主要提供三個方面的能力：人臉識別、人體識別、人臉對比，能力介紹

3、其中人臉識別、人體識別 目前主要是單個API的調用，不涉及多個API的協同調用，使用相對簡單(實例僅選擇一個API演示)。人臉對比涉及到人臉庫、樣本、圖片等的操作，需要多個API的協同操作：

4、代碼樣例
