Implement Contour Detection Using OpenCV

[Blindspot22]

Description:

• Detect contours in the binary image created by the thresholding step to identify the boundaries of moving objects.

Implementation Steps:

• Import the findContours function from OpenCV, which is used to detect contours in binary images.
• Apply the findContours function to the thresholded binary image to extract the contours of the moving objects.
• Configure the contour retrieval mode (e.g., RETR_EXTERNAL to retrieve only the external contours) and contour approximation method (e.g., CHAIN_APPROX_SIMPLE).
• Store the detected contours in a data structure for further processing, such as drawing bounding boxes.
• Test the contour detection by drawing the detected contours on the original frame using drawContours and displaying the result.
