US Patent 11460857 Object or person attribute characterization

A vehicle computing system may implement techniques to determine attributes (or intent) of an object detected by a vehicle operating in the environment. The techniques may include determining a set of features with respect to a detected object by a first model and determining, by a second model and based on the set of features, one or more attributes of the object. The first model and the second model may be configured to process at least one image frame to determine the one or more attributes of the object. A model may receive sensor data as an input, and output features and/or an attribute for the detected object. Based on the attribute(s) of the object, a vehicle computing system may control operation of the vehicle.
