    Abstract: In some examples, a first set of image data is received, the first set of image data corresponding to images of a first type and being of a person in an environment of a vehicle and including a first plurality of images of the person over a time interval. In some examples, a second set of image data is received, the second set of image data corresponding to images of a second type and being of the person in the environment of the vehicle and including a second plurality of images of the person over the time interval. In some examples, the first set of image data and the second set of image data are processed to determine a recognized action of the person, which includes using a first neural network to determine the recognized action of the person.

    Abstract: According to one aspect, causal graph chain reasoning predictions may be implemented by generating a causal graph of one or more participants within an operating environment including an ego-vehicle, one or more agents, and one or more potential obstacles, generating a prediction for each participant within the operating environment based on the causal graph, and generating an action for the ego-vehicle based on the prediction for each participant within the operating environment. Nodes of the causal graph may represent the ego-vehicle or one or more of the agents. Edges of the causal graph may represent a causal relationship between two nodes of the causal graph. The causal relationship may be a leader-follower relationship, a trajectory-dependency relationship, or a collision relationship.

    Abstract: According to one aspect, weakly-supervised action segmentation may include performing feature extraction to extract one or more features associated with a current frame of a video including a series of one or more actions, feeding one or more of the features to a recognition network to generate a predicted action score for the current frame of the video, feeding one or more of the features and the predicted action score to an action transition model to generate a potential subsequent action, feeding the potential subsequent action and the predicted action score to a hybrid segmentation model to generate a predicted sequence of actions from a first frame of the video to the current frame of the video, and segmenting or labeling one or more frames of the video based on the predicted sequence of actions from the first frame of the video to the current frame of the video.

    Abstract: Systems and methods for estimating velocity of an autonomous vehicle and state information of a surrounding vehicle are provided. In some aspects, the system includes a memory that stores instructions for executing processes for estimating velocity of an autonomous vehicle and state information of the surrounding vehicle and a processor configured to execute the instructions. In various aspects, the processes include: receiving image data from an image capturing device; performing a ground plane estimation by predicting a depth of points on a road surface based on an estimated pixel-level depth; determining a three-dimensional (3D) bounding box of the surrounding vehicle; determining the state information of the surrounding vehicle based on the ground plane estimation and the 3D bounding box; and determining the velocity of the autonomous vehicle based on an immovable object relative to the autonomous vehicle. In some aspects, an operation of the autonomous vehicle may be controlled based on at least one of the state information or the velocity of the autonomous vehicles.

    Abstract: A vehicle includes a ranged sensor that generates time-series data indicating positions of objects in an environment surrounding the vehicle, a user interface configured to warn the driver of a predicted collision between the vehicle and one of the objects in the environment, and at least one processor including an ECU operatively connected to the ranged sensor and the user interface. The processor records control inputs by the driver driving the vehicle, and develops a driver behavior model associated with the driver driving the vehicle based on the control inputs. The processor also predicts trajectories of the objects and the vehicle based on the time-series data and the driver behavior model, and predicts a collision between the vehicle and one of the objects based on the predicted trajectories. The processor also generates a warning indicating the predicted collision to the driver.

The system and method further include predicting future trajectories of the agents located within the surrounding environment of the ego vehicle and a future ego motion of the ego vehicle within the surrounding environment of the ego vehicle based on the annotated actions.
