Python实现AI换脸功能

需要用到的接口：

获取人脸信息的接口：https://api-cn.faceplusplus.com/facepp/v3/detect

实现换脸的接口 ：https://api-cn.faceplusplus.com/imagepp/v1/mergeface

代码分为三步

代码：

import requests
import json
import simplejson
import base64

#第一步：获取人脸关键点
def find_face(imgpath):
 """
 :param imgpath: 图片的地址
 :return: 一个字典类型的人脸关键点 如：{'top': 156, 'left': 108, 'width': 184, 'height': 184}
 """
 http_url = 'https://api-cn.faceplusplus.com/facepp/v3/detect' #获取人脸信息的接口
 data = {
 "api_key":"x2NyKaa6vYuArYwat4x0-NpIbM9CrwGU",#访问url所需要的参数
 "api_secret":"OuHx-Xaey1QrORwdG7QetGG5JhOIC8g7",#访问url所需要的参数
 "image_url":imgpath, #图片地址
 "return_landmark":1
 }


 files = {'image_file':open(imgpath,'rb')} #定义一个字典存放图片的地址
 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

#第二步：实现换脸
def merge_face(image_url1,image_url2,image_url,number):
 """
 :param image_url1: 被换脸的图片路径
 :param image_url2: 换脸的图片路径
 :param image_url: 换脸后生成图片所保存的路径
 :param number: 换脸的相似度
 """
 #首先获取两张图片的人脸关键点
 face1 = find_face(image_url1)
 face2 = find_face(image_url2)
 #将人脸转换为字符串的格式
 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']))
 #读取两张图片
 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()

 url_add = 'https://api-cn.faceplusplus.com/imagepp/v1/mergeface' #实现换脸的接口
 data={
 "api_key": "x2NyKaa6vYuArYwat4x0-NpIbM9CrwGU",
 "api_secret": "OuHx-Xaey1QrORwdG7QetGG5JhOIC8g7",
 "template_base64":f1_64,
 "template_rectangle":rectangle1,
 "merge_base64":f2_64,
 "merge_rectangle":rectangle2,
 "merge_rate":number
 }
 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__':
 image1 = r"meizi1.jpg"
 image2 = r"meizi.jpg"
 image3 = r"face1.jpg"
 merge_face(image1,image2,image3,100)

效果：

换脸前

要换的脸：

换脸后：
