    Abstract: Systems and methods are provided for navigating an autonomous vehicle using reinforcement learning techniques. In one implementation, a navigation system for a host vehicle may include at least one processing device programmed to: receive, from a camera, a plurality of images representative of an environment of the host vehicle; analyze the plurality of images to identify a present navigational state associated with the host vehicle; determine a first potential navigational action for the host vehicle based on the identified present navigational state; determine a first indicator of an expected reward based on the first potential navigational action and the identified present navigational state; predict a first future navigational state based on the first potential navigational action; determine a second indicator of an expected reward associated with at least one future action determined to be available to the host vehicle in response to the first future navigational state; determine a second potential navigational action for the host vehicle based on the identified present navigational state; determine a third indicator of an expected reward based on the second potential navigational action and the identified present navigational state; predict a second future navigational state based on the second potential navigational action; determine a fourth indicator of an expected reward associated with at least one future action determined to be available to the host vehicle in response to the second future navigational state; select the second potential navigational action based on a determination that, while the expected reward associated with the first indicator is greater than the expected reward associated with the third indicator, the expected reward associated with the fourth indicator is greater than the expected reward associated with the first indicator; and cause at least one adjustment of a navigational actuator of the host vehicle in response to the selected second potential navigational action.

    Abstract: The present disclosure relates to a navigation system for a host vehicle. The system may include a processing device programmed to receive, from a camera, a plurality of images representative of an environment of the host vehicle; analyze the plurality of images to identify at least one pedestrian in the environment of the host vehicle; cause at least one adjustment of a navigational system of the host vehicle to signal to the pedestrian a navigational intent of the host vehicle; analyze the plurality of images to detect a potential reaction of the pedestrian to the at least one adjustment of the navigational system of the host vehicle; determine a navigational action for the host vehicle based on a detected potential reaction of the pedestrian; and cause at least one adjustment of a navigational actuator of the host vehicle in response to the determined navigational action for the host vehicle.

    Abstract: Various driver assistance systems mountable in a host vehicle and computerized methods for detecting a vertical deviation of a road surface. The driver assistance system includes a camera operatively connectible to a processor. Multiple consecutive image frames are captured from the camera including a first image of the road and a second image of the road. Based on the host vehicle motion, the second image is warped toward the first image to produce thereby a warped second image. Image points of the road in the first image and corresponding image points of the road in the warped second image are tracked. Optical flow is computed between the warped second image to the first image. The optical flow is compared with an optical flow based on a road surface model to produce a residual optical flow. The vertical deviation is computed from the residual optical flow.
