'Go & Stop' sequence

Original sequence with alert
"Too small motion!"
This graph shows the dominant apical angles from pairs of successive images.
The alert has been shown when the dominant apical angle is under one degree.

'Pedestrian' sequence

Original sequence with alert
"Too small motion!"
This graph shows the dominant apical angles from pairs of successive images.
The alert has been shown when the dominant apical angle is under 0.5 degree.

Non-stabilized (left): Pedestrian detection (green rectangles) in perspective cutouts without  the stabilization.
Stabilized (right): Pedestrian detection in perspective  cutouts  with stabilized horizon (red  lines) computed by using the camera  trajectories of structure from motion.
