Python implements AI face change function

Need to use the interface:

Interface for obtaining face information: https://api-cn.faceplusplus.com/facepp/v3/detect

Realize the interface for face change: https://api-cn.faceplusplus.com/imagepp/v1/mergeface

The code is divided into three steps

Code:

import requests
import json
import simplejson
import base64

# Step 1: Get the key points of the face
def find_face(imgpath):"""
 : param imgpath:The address of the picture
 : return:The key points of a dictionary type face are as follows:{'top':156,'left':108,'width':184,'height':184}"""
 http_url ='https://api-cn.faceplusplus.com/facepp/v3/detect' #Interface for obtaining face information
 data ={"api_key":"x2NyKaa6vYuArYwat4x0-NpIbM9CrwGU",#Parameters required to access URL
 " api_secret":"OuHx-Xaey1QrORwdG7QetGG5JhOIC8g7",#Parameters required to access URL
 " image_url":imgpath, #The map's address
 " return_landmark":1}

 files ={'image_file':open(imgpath,'rb')} #Define the address of a dictionary to store pictures
 response = requests.post(http_url,data=data,files=files)
 res_con1 = response.content.decode('utf-8')
 res_json = simplejson.loads(res_con1)
 faces = res_json['faces']
 list = faces[0]
 rectangle = list['face_rectangle']return rectangle

# Step 2: Realize face change
def merge_face(image_url1,image_url2,image_url,number):"""
 : param image_url1:The image path of the changed face
 : param image_url2:Picture path for face change
 : param image_url:The path where the picture is saved after changing the face
 : param number:Similarity of face change
 """
 # First get the key points of the faces of the two pictures
 face1 =find_face(image_url1)
 face2 =find_face(image_url2)
 # Convert face to string format
 rectangle1 =str(str(face1['top'])+","+str(face1['left'])+","+str(face1['width'])+","+str(face1['height']))
 rectangle2 =str(str(face2['top'])+","+str(face2['left'])+","+str(face2['width'])+","+str(face2['height']))
 # Read two pictures
 f1 =open(image_url1,'rb')
 f1_64 = base64.b64encode(f1.read())
 f1.close()
 f2 =open(image_url2,'rb')
 f2_64 = base64.b64encode(f2.read())
 f2.close()

 }
 response1 = requests.post(url_add,data=data)
 res_con1 = response1.content.decode('utf-8')
 res_dict = json.JSONDecoder().decode(res_con1)
 result = res_dict['result']
 imgdata = base64.b64decode(result)
 file=open(image_url,'wb')
 file.write(imgdata)
 file.close()if __name__ =='__main__':

 image2 = r"meizi.jpg"
 image3 = r"face1.jpg"merge_face(image1,image2,image3,100)
