Refactoring Drowsiness Detection System

Issue Link: hassaanahmed04/Drowsiness-Detection-System #1
Issue Details: The current code implements a Drowsiness Monitoring System, combining image processing techniques with GUI elements using Tkinter. While the functionality is in place, there are opportunities for improvement in terms of code organization and readability.

Proposed Changes:

1. Modularize the code: Broke down the code into smaller, well-defined functions or classes to improve code structure and readability.

2. Add comments: Document complex logic or provide context for certain operations to enhance code understanding.

3. Use meaningful variable and function names: Ensured that variable and function names are descriptive and follow a consistent naming convention.

4. Implement error handling: Added appropriate error handling to handle scenarios where files or resources may not be found.

5. Use os.path.join(): Utilized this function to construct file paths, ensuring compatibility across different operating systems.
   Expected Outcome: The refactored code should maintain the functionality of the Drowsiness Monitoring System while significantly improving its readability, maintainability, and adherence to coding best practices.

Research and Challenges: Understanding the existing codebase and identifying areas for improvement required careful examination. Ensuring compatibility across different operating systems was a key challenge. Interactions with Maintainers: No direct interactions with maintainers for this issue. Difficulties Faced and Solutions: Refactoring a complex system like the Drowsiness Monitoring System required a systematic approach. Breaking down the code into smaller functions and adding comments greatly enhanced code comprehension
