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.

Abstract: This disclosure describes systems and methods for ranking routes based on driving complexity. An example method may include receiving one or more inputs, the one or more inputs including at least a starting location, a destination location, and a user driving experience level.

The example method may also include determining that the first difficulty value is less than the second difficulty value. The example method may also include automatically updating, prior to a first vehicle trip, a navigation system to the first route based on the determination that the first difficulty value is less than the second difficulty value.

Abstract: First objects are detected in an infrared image from an infrared camera and second objects are detected in a color image from a color camera. The first objects are compared with the second objects to determine pairs of matching first objects and second objects. For each matching pair, a respective region of an output image is colorized by setting colors of pixels in the region based on colors of the pixels of the second object in the matching pair. The pixels in the region have locations corresponding to the locations of the pixels in the first object of the matching pair. When the colorizing is complete, pixels not in the colorized regions have intensities of the infrared image. The output image is a version of the infrared image with a region colorized according to the color image.

Abstract: Vision sensor dynamic watermarking via noise characterization are disclosed herein. An example device can capture an image by a first device, where the image comprising a pixel group has baseline noise characterization caused by a base noise profile for the first device.
