阿裡雲視覺智能開放平台--人臉識别使用教程

概述

人臉人體識别技術是基于阿裡雲深度學習算法，結合圖像或視訊的人臉檢測、分析、比對以及人體檢測等技術，為您提供人臉人體的檢測定位、人臉屬性識别和人臉比對等能力。可以為開發者和企業提供高性能的線上API服務，應用于人臉AR、人臉識别和認證、大規模人臉檢索、照片管理等各種場景。

1、服務開通，參考連結：

阿裡雲視覺智能開放平台使用簡明教程

2、目前主要提供三個方面的能力：人臉識别、人體識别、人臉對比，

能力介紹

3、其中人臉識别、人體識别目前主要是單個API的調用，不涉及多個API的協同調用，使用相對簡單(執行個體僅選擇一個API示範)。人臉對比涉及到人臉庫、樣本、圖檔等的操作，需要多個API的協同操作：
