Detection Status for Abandoned Object Detection
All moving objects detected are shown with contour lines.
If [Object Size (%)] and [Duration (Sec)] are not exceeded, contour lines are white.
If both [Object Size (%)] and [Duration (Sec)] are exceeded, the contour lines take on the same color as the detection
area, indicating that "detected" mode has been triggered.
