This paper proposes a vision-based framework that maps SLZs in dynamic scenes by integrating several functionalities for analyzing visually static and dynamic aspects of a scene.

We tested our framework on different operational scenarios, including urban and natural scenes with moving objects like vehicles and pedestrians.
