人臉比對

import requests
from json import JSONDecoder

定義一個函數，用於比較兩個圖像的人臉相似度

def compareimage(filepath1 ,filepath2):  #人臉比對
    try:
        http_url = "https://api-cn.faceplusplus.com/facepp/v3/compare"
        key = "****"  #輸入你的API Key
        secret = "****" #輸入你的 API Secret
        data = {"api_key":key, "api_secret": secret}
        files = {"image_file1": open(filepath1, "rb"),"image_file2": open(filepath2, "rb")} #打開兩個圖像文件
        response = requests.post(http_url, data=data, files=files)  #進行辨識
        req_con = response.content.decode('utf-8')  #取得結果
        req_dict = JSONDecoder().decode(req_con)  #將結果轉為字典
        confidence = req_dict['confidence']  #取得相似度
        return confidence
    
    except Exception as e:
      print("無法識別！")
      return 0

比較兩個圖像中的人臉相似度並顯示結果

def showcompare(filepath1 ,filepath2):
    result = compareimage(filepath1 ,filepath2)
    print('相似度指數=' + str(result))
    if result >= 75:
        print(filepath1+' 和 '+filepath2+' 為同一人！')
    else:
        print(filepath1+' 和 '+filepath2+' 為不同人！')


showcompare('/content/David1.jpg', '/content/face1.jpg') #放入要比對照片的路徑
showcompare('/content/jeng1.jpg', '/content/face1.jpg')  #放入要比對照片的路徑
