The Perception Component consists of the following sub-components:

- **Object Recognition**: Recognizes dynamic objects surrounding the ego vehicle in the current frame and predicts their future trajectories.
- **Obstacle Segmentation**: Identifies point clouds originating from obstacles(not only dynamic objects but also static obstacles that should be avoided, such as stationary obstacles) that the ego vehicle should avoid.
- **Object Recognition**: Recognizes dynamic objects surrounding the ego vehicle in the current frame, objects that were not present during map creation, and predicts their future trajectories. This includes:
- Pedestrians
- Cars
- Trucks/Buses
- Bicycles
- Motorcycles
- Animals
- Traffic cones
- Road debris: Items such as cardboard, oil drums, trash cans, wood, etc., either dropped on the road or floating in the air
- **Obstacle Segmentation**: Identifies point clouds originating from obstacles, including both dynamic objects and static obstacles that requires the ego vehicle either steer clear of them or come to a stop in front of the obstacles.
- This includes:
- All dynamic objects (as listed above)
- Curbs/Bollards
- Barriers
- Trees
- Walls/Buildings
- This does not include:
- Grass
- Water splashes
- Smoke/Vapor
- Newspapers
- Plastic bags
- **Occupancy Grid Map**: Detects blind spots (areas where no information is available and where dynamic objects may jump out).
- **Traffic Light Recognition**: Recognizes the colors of traffic lights and the directions of arrow signals.
