Implement MOG2 Background Subtraction

[Blindspot22]

Description:

• Implement the MOG2 (Mixture of Gaussians) algorithm for background subtraction to isolate moving objects from the background.

Implementation Steps:

• Import the necessary OpenCV modules required for background subtraction, particularly the BackgroundSubtractorMOG2.
• Initialize the MOG2 background subtractor using BackgroundSubtractorMOG2::default.
• Integrate the background subtractor into the video processing loop, applying it to each captured frame.
• Retrieve the foreground mask (binary image) where the moving objects are white, and the background is black.
• Test the implementation by displaying the foreground mask and adjusting parameters such as the history, variance threshold, and detect shadows.
