阿里云视觉智能开放平台--人脸识别使用教程

概述

人脸人体识别技术是基于阿里云深度学习算法，结合图像或视频的人脸检测、分析、比对以及人体检测等技术，为您提供人脸人体的检测定位、人脸属性识别和人脸比对等能力。可以为开发者和企业提供高性能的在线API服务，应用于人脸AR、人脸识别和认证、大规模人脸检索、照片管理等各种场景。

Step By Step

1、服务开通，参考链接：阿里云视觉智能开放平台使用简明教程

2、目前主要提供三个方面的能力：人脸识别、人体识别、人脸对比，能力介绍

3、其中人脸识别、人体识别 目前主要是单个API的调用，不涉及多个API的协同调用，使用相对简单(实例仅选择一个API演示)。人脸对比涉及到人脸库、样本、图片等的操作，需要多个API的协同操作：

4、Code Sample
