Title: "Python code for a webcam motion detector"
Search Term: "Python webcam motion detection" Software: A Python IDE (such as PyCharm, IDLE, or Jupyter Notebook) and OpenCV library
Explanation:
- The code starts the webcam and captures the first frame as the reference frame. It converts the first frame to grayscale for easy comparison.
- It then reads the webcam frames in a while loop, converts them to grayscale, and calculates the absolute difference between the current frame and the first frame.
- It applies a threshold to the difference image to create a binary image, where white pixels represent motion and black pixels represent no motion.
- The code then shows the difference image, which highlights any motion in the webcam view, and exits the loop when the 'q' key is pressed.
- It releases the webcam and closes all windows at the end of the script.
