1. A system comprising:
one or more processing units to execute operations comprising:
receiving image data generated using one or more cameras, the image data representative of one or more images depicting one or more objects illuminated by one or more headlights of a vehicle;
based at least on determining a first region of the one or more images that corresponds to the one or more objects, computing one or more contrast values corresponding to the first region of the one or more images;
determining, using the one or more contrast values and for a plurality of pixels in the first region, that a ratio between luminance of the plurality of pixels and luminance corresponding to a second region of the one or more images is greater than a threshold; and
based at least on the ratio being greater than the threshold, transmitting data to cause an adjustment to one or more parameters of the one or more headlights.
