Suggestion: Refactor the test cases to use a setup method for creating the detector and loading the images. This will avoid repetition and make the tests cleaner.

Question: What is the best change that can be introduced in this pull request?

Answer:
The best change introduced in this pull request is the addition of unit tests for the DiffMotionDetector class in the motion_detection.py file. These tests cover various scenarios including setting the background image, returning a binary image after the detection process, and handling None values for both background and foreground images. This will help ensure the functionality of the DiffMotionDetector class and make the codebase more robust and reliable. It also encourages a Test-Driven Development (TDD) approach, which is a good practice in software development.
