人脸识别系统代码--单人脸提取

1.导入所需的库：

Tkinter用于GUI，face_recognition用于人脸识别，PIL用于图像处理，subprocess用于运行其他Python脚本。

import tkinter as tk
from tkinter import filedialog
import face_recognition
from PIL import Image, ImageTk
import subprocess

2.设置窗口

创建一个Tkinter窗口，设置标题和大小。

win = tk.Tk()
win.title('Welcome')
win.geometry('750x600')

3.设置背景

设置窗口背景为一张GIF图片，并调整图片大小以适应窗口。

image = Image.open("9.gif")
image = image.resize((750, 600))  # 调整背景图片大小
photo1 = ImageTk.PhotoImage(image)
canvas = tk.Label(win, image=photo1)
canvas.pack()

1. 定义全局变量

 定义全局变量file_path和face_image_label，用于存储文件路径和人脸图像标签。

file_path = None
face_image_label = None

1. 定义函数xz

用于打开文件对话框，让用户选择一张图片，并将其显示在窗口中。

def xz():
    global file_path
    file_path = filedialog.askopenfilename(title="选择图片",
                                           filetypes=(("图片文件", "*.png *.jpg *.jpeg *.bmp"),
                                                      ("所有文件", "*.*")))
    if file_path:
        image = Image.open(file_path)
        image = image.resize((370, 450))
        photo = ImageTk.PhotoImage(image)
        image_label = tk.Label(win, image=photo)
        image_label.image = photo
        image_label.place(x=10, y=100)

6.定义函数tq

用于识别人脸，并将识别出的人脸显示在窗口中。

def tq():
    global file_path, face_image_label
    if file_path:
        img = face_recognition.load_image_file(file_path)
        face_locations = face_recognition.face_locations(img, model='hog')

        for i, face_location in enumerate(face_locations):
            top, right, bottom, left = face_location
            face_img = img[top:bottom, left:right]

            face_name = f"face_{i}.jpg"
            face_image = Image.fromarray(face_img)
            face_image = face_image.resize((100, 100))
            face_photo = ImageTk.PhotoImage(face_image)

            if face_image_label:
                face_image_label.destroy()

            face_image_label = tk.Label(win, image=face_photo)
            face_image_label.image = face_photo
            face_image_label.place(x=430, y=100)

 7.定义函数close

用于关闭当前窗口并打开另一个Python脚本提取.py。

def close():
    win.destroy()  # 先关闭当前窗口
    subprocess.Popen(["python", "提取.py"])  # 再打开新的脚本

8.设置按钮

image = Image.open("A.gif")  # 加载一张图片
photo2 = ImageTk.PhotoImage(image)
bt1 = tk.Button(win, image=photo2, width=198, height=32,command=xz)
bt1.place(x=30, y=30)

image = Image.open("F3.gif")  # 加载一张图片
photo3 = ImageTk.PhotoImage(image)
bt2 = tk.Button(win, image=photo3, width=198, height=32,command=tq)
bt2.place(x=275, y=30)

image = Image.open("B.gif")  # 加载一张图片
photo4 = ImageTk.PhotoImage(image)
bt3 = tk.Button(win, image=photo4, width=198, height=32,command=close)
bt3.place(x=520, y=30)

1. 退出窗口

win.mainloop()
