1.实验内容
1．Python综合应用：爬虫、数据处理、可视化、机器学习、神经网络、游戏、网络安全等。
很久以前我注意到一个问题，就是我经常离开电脑时忘记熄屏，虽然可能我离开的时间很短，但是会不会有人动我的电脑（虽然里面也没什么东西可看），但是可能有些人的电脑里有重要文件信息，那他们可能很需要有一款程序来帮助他们。所以我决定写一个人脸识别检测来获取计算机控制权的程序。（不打算写游戏的原因是觉得看到身边的人沉迷游戏，对社会的发展和人类文明的进步没有丝毫的作用）
2.实验过程及结果
1.选择程序所需要的库
凭我现在的水平，想弄一个人脸识别简直就是天方夜谭，但是，python之所以强大，一个充分必要条件就是python的第三方库太多太强大了，上百度上一查就发现了face-recognition库（以下简称FR），网传识别成功率高达99.8%，FR是通过计算面部关键点来进行比对从而实现人脸识别的库，我们可以通过更改FR文件的容错率和敏感度来提高识别的准确度和精度（为下文埋下伏笔）。这样一来我就完成了整个程序最关键的一步。
2.流程
首先就是设计FASS的结构，最初在开始写的时候，并没有考虑这个流程和框架的东西，所以导致了函数运行到这里就不知道下一步该干什么了。后来在MOOC上看python爬虫的课时，主讲老师也是先将对象都写出来，然后再一点一点地将函数写入，逻辑比我清晰，难怪最开始那几天我怎么写都不对。
然后我准备开始导入库，其他库还好，可就是face-recognition和opencv这两个库在安装时出现了问题。opencv安装时是报错pip的问题，我也看不懂cmd讲了什么，就只好百度，结果在更新pip之后，就可以正常安装了。但是FR库就有鬼了。怎么安装都不对，百度上的方法都试了也没用，cmd的报错一下子就一百多行，心态直接爆炸，黄色红色的报错都有，没办法，一行一行看，果然我看到了要求安装visual studio和c++模块才能运行，vs的文件配置我的电脑一直就有问题，从微软官网上下载的exe文件不行，所幸HP自带了visual studio installer，等它自己安装完，再试试，还要安装dlib和一堆配置，才完成了FR库的安装。
又一个难点是cv2的图片获取和PIL的图片存储与读取，尤其是在存储上，因为废物是我，网上的都是大佬，他们只说精华和难点，所以再存储图片的路径上出了大问题，我一直以为image.save（）里面填的的文件名，结果应该填写图片名称。裂开。
def adding_face(self):

tk.messagebox.showinfo(title='Please Wait', message='Connecting Packages...\nWhen control the Face Capture,\n\
press p to capture a photo and q to quit\nYou can push your photo into file face_database instead')
capture = cv2.VideoCapture(0, cv2.CAP_DSHOW)
width = 1000
height = 618
w = 360
capture.set(cv2.CAP_PROP_FRAME_WIDTH, width)
capture.set(cv2.CAP_PROP_FRAME_HEIGHT, height)
crop_w_start = (width - w) // 2
crop_h_start = (height - w) // 2
while True:
ret, frame = capture.read()
frame = frame[crop_h_start:crop_h_start + w,
crop_w_start:crop_w_start + w]
frame = cv2.flip(frame, 1, dst=None)
cv2.imshow("Face Capture", frame)
det_bp = cv2.waitKey(1) & 0xFF
if det_bp == ord('p'):
way = os.getcwd()
cv2.imwrite("fdb_face.jpg", cv2.resize(frame, (224, 224)))
img = Image.open("fdb_face.jpg")
img.save(way + r'\face_database\fdb_face.jpg')
os.remove(way + r'\fdb_face.jpg')
capture.release()
cv2.destroyAllWindows()
return False
elif det_bp == ord('q'):
capture.release()
cv2.destroyAllWindows()
return False
接着是创建GUI，虽然刘子谦学长给我推荐了一个qtdesigner的软件，界面是好设计，但是函数的添加并不熟悉，所以我还是选用了tkinter进行GUI的设计，通过stringvar实现了用户名和密码的输入，button实现了按钮，还有window实现了界面的转化。但是在这里在界面转化的时候发生了循环导致无法关闭的情况，csdn里的大神说，不应该使用window.mainloop,而是应该要定义root，使用root.mainloop实现界面的完全关闭。
def login__init__(self):
"""

including email and passcode input

and login in and quit choices
"""
self.window = tk.Tk()
self.window.title('Welcome to FASS')
self.window.geometry('300x185')
tk.Label(self.window, text='Email').place(x=135, y=20)
tk.Label(self.window, text='Passcode\n(Any sentence you like can be your passcode)').place(x=20, y=70)
self.var_email = tk.StringVar()
enter_email = tk.Entry(self.window, textvariable=self.var_email)
enter_email.place(x=80, y=50)
self.var_passcode = tk.StringVar()
enter_passcode = tk.Entry(self.window, textvariable=self.var_passcode, show='*')
enter_passcode.place(x=80, y=110)
self.bt_login = tk.Button(self.window, text='Login In', command=self.login)
self.bt_login.place(x=40, y=140)
self.bt_quit = tk.Button(self.window, text='Quit', command=self.quit)
self.bt_quit.place(x=210, y=140)
关于邮件提醒，需要接口的支持，还好我关注了一个叫做“码农升级”的公众号，里面不定期更新一些关于python的文章和小程序。其中就有自动发送邮件的代码。（成也萧何，败也萧何，里面有一些整蛊人的小程序，我将这些代码生成exe文件后发给同学，结果现在请他们帮我测试程序都不帮我了，再也不喊狼来了）
def email_send(self):
"""

"""
doc = open('email.txt', 'r')
self.login.email = doc.read()
email = EmailMessage()
email['from'] = 'FASS Guard'
email['to'] = f'{self.email}'
email['subject'] = 'Warning'
email.set_content("Your Fass verification failed, Please pay attention to your computer!")
with smtplib.SMTP(host='smtp.gmail.com', port=587) as smtp:
smtp.ehlo()
smtp.starttls()
smtp.login(f"{self.email}", f"{self.emailpasscode}")
smtp.send_message(email)
完成了这些，FASS最基本的功能也就基本上完成了，然后进行优化，目前版本是FASS2.0.1，附上完整代码。

3.结果
附几张图就行，找了一个跟我长得差不多的人的头像遮住我的脸。这只是FASS2.0.1的版本，其中必然还有很多用着不舒服的地方和bug，等我接下来更新出Beta版本并找其他同学进行测试后，我会把exe文件放在网上，虽然学习是前提，源码可以开源，不过其中的法律规定还是要遵守。
