一.腾讯优图

1.开发者地址：http://open.youtu.qq.com/welcome/developer

2.接入流程：按照开发者页面的接入流程接入之后，创建应用即可获得所需的AppID、SecretID和SecretKey这是进行接口调用必须的凭证

3.测试流程：

3.1.测试可以直接调用网络接口，或者下载相应语言的sdk(http://open.youtu.qq.com/welcome/developer#/tool-sdk)，我采用的是下载python版本的sdk(该sdk对应的python2.x的版本)

3.2.测试的数据还是lfw的数据集，测试结果如果调用成功则获取到比对的分数，调用失败则将改组比对的分数设置为-1，以便后续的分析，直接上python代码：

1 import TencentYoutuyun #这是下载的python模块

2

3 appid = 'xxxxx' #你的appid

4 secret_id = 'xxxxx' #你的secret_id

5 secret_key = 'xxxxx' #你的secret_key

6 userid = 'test' #任意字符串

7 end_point =TencentYoutuyun.conf.API_YOUTU_END_POINT8 youtu =TencentYoutuyun.YouTu(appid, secret_id, secret_key, userid, end_point)9

13 res_file = open("youtu.txt", "a+") #txt保存比对分数

14 error_code = open("error_code.txt", "a+") #测试用于保存调用出错编码

15 count =016 while 1:17 image_path = "xxxxxx" #你本地lfw数据的路径

二.知脸(ZKfaceOnline)

1.知脸开发者中心地址：http://zkfaceonline.com:8003/developers_doc.html

2.接入流程：注册后可获取到Ocp-Apim-Subscription-Key，然后再开发者管理界面注册人脸比对数据库，记住该数据库的名称，该名称以及Ocp-Apim-Subscription-Key在后面的测试过程中都是必需的。

3.测试流程：

3.1.人脸比对分为两个步骤：先将需要比对的两张图片上传到指定接口做人脸特征的提取，如果成功则返回这两张图片在数据库中faceid，然后将返回的两个faceid提交到指定的人脸比对接口做比对，如果比对成功则会返回两张图片之间的相似值

3.2.具体测试代码，如下：

1 #coding=utf-8

2 import requests #该模块是第三方库，可以去网上下载

3 importjson4

5

6 def get_face_id(image): #上传一张图片做人脸检测，返回faceid

三.性能评测

建议采用画rock曲线的方式进行比较，可以将百度和face++的人脸比对结果画在一张图上进行比对
