Create Unit Tests for Background Subtraction

[Blindspot22]

Description:

• Develop comprehensive unit tests to validate the functionality and robustness of both the MOG2 and KNN background subtraction implementations.

Implementation Steps:

• Set up a testing framework in the Rust project using cargo test.
• Write unit tests to verify that the MOG2 background subtractor correctly identifies moving objects and generates accurate foreground masks.
• Write unit tests to verify the KNN background subtractor's performance under various conditions (e.g., different lighting, motion speeds).
• Create test cases that simulate common scenarios, such as sudden changes in lighting or the introduction of new static objects, to ensure the algorithms handle these cases gracefully.
• Run all tests to validate the background subtraction functionality, ensuring that both MOG2 and KNN produce consistent and reliable results.
