[Python] Realize face recognition

foreword

hi hi everyone

Let's implement face recognition with Python today?

ask you a question

What is Baidu Aip module?

Cough cough, Baidu AI platform provides a lot of API interfaces for developers to quickly call and use in
projects

In addition to face recognition, the same is true for calling other api functions.

Preparation

local environment

System: win11
Python version: 3.9.7
Editor: VS2022

Install baidu-aip module

win + R enter cmd to open the command prompt

Execute and install Baidu AI module

pip install baidu-aip

Log in to Baidu AI platform to create applications

Open the Baidu AI platform to log in
and find face recognition in the console

create application

Create applications according to your own requirements

Finally get the AppID API Key Secret Key of the application

Make a note of the value and so on will use

AppID：10000000
API Key：xxxxxxxxxxxxxxxxxxxxxxxx
Secret Key：xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

code flow

Import baidu-aip module

Original code. Click to receive [Remarks: Su]

Open VS2022 (VSCode PyCharm Sypder is equivalent) to create a py file
input

from aip import AipFace

Declare the AppID API Key Secret Key obtained above

APP_ID = '10000000'
API_KEY = 'xxxxxxxxxxxxxxxxxxxxxxxx'
SECRET_KEY = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

Initialize Baidu AIP face recognition module

client = AipFace(APP_ID, API_KEY, SECRET_KEY)

Create a face detection function

def face_detect(image):
    result = client.detect(image, image_type='BASE64')
    print(result)
    return result

The input picture image must be in BASE64 format

Convert pictures to BASE64 format

Import the base64 package

import base64

Open the image as BASE64 format

But importing into Baidu AI needs to be in string format, so it is returned as a string

def imageToBase64(imagePath):
    with open(imagePath, 'rb') as f:
        image = base64.b64encode(f.read())
        return str(image, encoding='utf-8')

Open the image for detection

First prepare a picture pic1.jpg

Call functions

face_detect(imageToBase64("pic1.jpg"))

Prompt that the call is successful:

the problem encountered

Prompt at runtime:

requests.exceptions.ProxyError: HTTPSConnectionPool(host='aip.baidubce.com', port=443)

win + R, enter regedit to open the registry, find

\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

Change the value of ProxyEnable to 0
and run again

Extend to use other functions

In addition to face detection, you can also use functions such as face comparison and face search, and the calling method is the same, such as face comparison.

def face_match(image1, image2):
    result = client.match([
    {
    
    
        'image': image1,
        'image_type': 'BASE64',
    },
    {
    
    
        'image': image2,
        'image_type': 'BASE64',
    }
   ])
    print(result)
    return result

face search

def face_search(image,group_id_list):
    result = client.search(image, image_type='BASE64',group_id_list=group_id_list)
    print(result)
    return result

APP_ID API_KEY SECRET_KEY needs to be modified to your own
