The motion detection over a single frame can be decomposed into four steps: (stream parallel compu tation)
- Pick the frame from the input video.
- Turn the frame to greyscale.
- Smooth the frame.
- Detect motion computing the percentage of different pixels between the background picture and
the frame.
The sequential solution performs an infinite loop which retrieves the frame from the input video,
checks if it has motion and stops when the frame retrieved from the video is empty.
The actual motion detection is implemented by comparing pixel by pixel the frame and the reference background picture.
The utilities to handle frame capturing, elaboration and motion detection have been implemented into a
dedicated object MotionDetector.
