Simple Motion Detection

Any movement should result in a change in the video image

1. Save previous frame of video data
2. Get new frame of video data
3. Compare corresponding pixels from each frame - find ones that are different
4. Many changes within an area = motion in that area

Video noise makes this imperfect - parameters will have to be tweaked

Examples:

• motion.py
• motion2.py
• vidinteract.py
• vidinteract2.py
