以下是对代码进行的优化

1. 添加了对代码的注释，使代码更易于理解。

2. 将双引号改为单引号，以符合 Python 代码规范。

3. 添加了标题、描述和关键字，以方便搜索引擎收录。

4. 对代码进行了格式化，使其更易于阅读。

5. 更改了用户登录信息的格式，并将用户存储在一个列表中。

6. 添加了对登录窗口和主窗口的显示，使程序更易于使用。

7. 在 stop_detection 方法中添加了等待时间，以确保所有线程都停止后再响应停止事件。

8. 在 stop_detection 方法中添加了对 stop 按钮的禁用，以避免用户多次点击导致程序出现异常。

9. 修改了对登录成功后的处理逻辑，添加了对主窗口的显示。

10. 在 stop_detection 函数中添加了等待时间，并设置了 stop 按钮的不可用状态，以确保所有线程都停止后再响应停止事件。

以下是对代码进行的优化建议

1. 可以使用更可靠的线程停止方法，例如使用信号量或其他同步机制。

2. 可以添加日志记录功能，以方便调试和排查问题。

3. 可以添加更多的安全检查，例如对用户输入进行验证。

4. 可以将代码模块化，以提高代码的可维护性和可扩展性。

5. 可以将代码封装成一个类，以提高代码的组织性和可重用性。
