1. A method for managing a headlight on a vehicle, the method comprising:
- receiving an image of an area in front of the vehicle to form a received image;
identifying a first set of features in the received image;
comparing the first set of features in the received image with a number of sets of features from a plurality of previous images, wherein each image in the plurality of previous images is associated with a headlight setting;
identifying a second set of features from a previous image in the plurality of previous images matching the first set of features in the received image; and
determining whether to change a setting for the headlight on the vehicle based on the headlight setting associated with the previous image,wherein the plurality of previous images comprises a first set of images associated with a high beam setting as the headlight setting and a second set of images associated with a low beam setting as the headlight setting and wherein identifying the second set of features from the previous image in the plurality of previous images matching the first set of features in the received image comprises;
