  • Publication number: 20260045076
    Abstract: Embodiments provide systems and methods that tailor, based on driving scenario for a vehicle: (1) operation of a neural network (used to process image data obtained during the driving scenario) to skip a determined number of neural layers; and (2) input scale for image data provided to the neural network. In this way, systems and methods can scale computational power and efficiency for image processing tasks as needed based on the nature and relative complexity of different driving scenarios.
