A first compression rule may be applied to portions of the image that include the area of interest. A second compression rule may be applied to portions of the image that exclude the area of interest.

Abstract: Systems and methods for ranking routes based on driving complexity are provided. The systems and methods may generate routes for a user based on factors indicative of difficulty levels of the routes (for example, based on the types of road features that exist on the route, among various other factors). The difficulty levels of the generated routes may then be used to automatically select, by a navigation system of a vehicle, a route that is suitable for the user based on their driving experience level. Alternatively, the routes may be presented to the user via the vehicle or a mobile device for selection by the user. The systems and methods may also be dynamic in that the difficulty levels of the routes may be adjusted as the user gains more driving experience.

Thermal data in the plurality of thermal images is normalized based on an ambient air temperature to generate a plurality of normalized thermal images. The plurality of normalized thermal images are input to a machine learning program trained to output an identification of an object based on the ambient air temperature and a risk of collision between the vehicle and the object. A vehicle component is actuated based on the identification of the object and the risk of collision with the object.

Abstract: A vehicle characterizes a sunload on the vehicle using an imaging system including at least one camera capturing image data (e.g., without using an ambient light sensor). The image data includes at least a portion of a passenger cabin. A region of interest (ROI) overlay receives the image data and extracts selected image data according to predetermined scene elements of the vehicle environment. An occupant overlay is configured to detect a vehicle occupant represented in the selected image data and configured to generate truncated image data by subtracting image data corresponding to the vehicle occupant from the selected image data. An ambient light model uses environmental parameters including a sun position to estimate an expected sunload range. A mapper generates a sunload map comprising respective sunload values for a plurality of locations on the vehicle according to the truncated image data and the expected sunload range.
