1 簡介

本文，基于曠視與百度API，調(diào)用獲得人臉檢測以及人臉屬性信息（年齡性別情緒種族等），
大批量調(diào)用時，本人實驗發(fā)現(xiàn)（約調(diào)用·3萬次）
曠視API的調(diào)用代碼簡單，耗時短（約100ms一次）
以上結(jié)論，因本人水平有限，僅限于本人實驗。

2 曠視 face++

• 官網(wǎng)web-demo在線演示
  

2.1 注冊

獲得 API Key

• 登錄曠視人工智能開放平臺，注冊后，在平臺內(nèi)申請API Key
  

2.2 調(diào)用API(以人臉檢測為例)

• 人臉檢測-文檔
• 人臉檢測-參考代碼
• 調(diào)用速度：約100毫秒/次

調(diào)用代碼

需要填上以上信息才能用

• key = “填上你的KEY”
  secret = “填上你的SECRET”
  filepath = r"本地圖片的路徑"

# -*- coding: utf-8 -*- import urllib.request import urllib.error import timehttp_url = 'https://api-cn.faceplusplus.com/facepp/v3/detect' key = "填上你的KEY" secret = "填上你的SECRET" filepath= r"本地圖片的路徑"boundary = '----------%s' % hex(int(time.time() * 1000)) data = [] data.append('--%s' % boundary) data.append('Content-Disposition: form-data; name="%s"\r\n' % 'api_key') data.append(key) data.append('--%s' % boundary) data.append('Content-Disposition: form-data; name="%s"\r\n' % 'api_secret') data.append(secret) data.append('--%s' % boundary) fr = open(filepath, 'rb') data.append('Content-Disposition: form-data; name="%s"; filename=" "' % 'image_file') data.append('Content-Type: %s\r\n' % 'application/octet-stream') data.append(fr.read()) fr.close() data.append('--%s' % boundary) data.append('Content-Disposition: form-data; name="%s"\r\n' % 'return_landmark') data.append('1') data.append('--%s' % boundary) data.append('Content-Disposition: form-data; name="%s"\r\n' % 'return_attributes') data.append("gender,age,smiling,headpose,facequality,blur,eyestatus,emotion,ethnicity,beauty,mouthstatus,eyegaze,skinstatus") data.append('--%s--\r\n' % boundary)for i, d in enumerate(data):if isinstance(d, str):data[i] = d.encode('utf-8')http_body = b'\r\n'.join(data)# build http request req = urllib.request.Request(url=http_url, data=http_body)# header req.add_header('Content-Type', 'multipart/form-data; boundary=%s' % boundary)try:# post data to serverresp = urllib.request.urlopen(req, timeout=5)# get responseqrcont = resp.read()# if you want to load as json, you should decode first,# for example: json.loads(qrount.decode('utf-8'))print(qrcont.decode('utf-8')) except urllib.error.HTTPError as e:print(e.read().decode('utf-8'))

將結(jié)果轉(zhuǎn)化為json

修改處

# results=qrcont.decode('utf-8')results = json.loads(qrcont)

2.3 API返回結(jié)果

2.3 異常

連接超時

CONCURRENCY_LIMIT_EXCEEDED

• 以上錯誤是，官方對免費的用戶請求頻率有限制，估計訪問頻次 2-5次/秒

3. 百度

• https://ai.baidu.com/tech/face/detect
• 調(diào)用性能：約20秒1次
  

3.0 調(diào)用參考

https://blog.csdn.net/cskywit/article/details/81540500

3.1 創(chuàng)建應用

獲得apikey / secrect-key

• 文檔（人臉檢測）

其中client_id 為官網(wǎng)獲取的AcessKey， client_secret 為官網(wǎng)獲取的Secrectkey

# encoding:utf-8 import requests # client_id 為官網(wǎng)獲取的AK， client_secret 為官網(wǎng)獲取的SK host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=【官網(wǎng)獲取的AK】&client_secret=【官網(wǎng)獲取的SK】' response = requests.get(host) if response:print(response.json())

3.2 調(diào)用代碼

首先需要獲得 access-token，

• 見代碼def get_access_token(self):
• 后續(xù)不需要執(zhí)行，注釋 access_token=baidu_faceDetect_api.get_access_token()

代碼需補充自己的信息
