Claim 0:
1. A method of determining relevance of a light source to an automobile, comprising:
capturing images, with at least one camera, of light sources in proximity to the automobile and sending captured images to a controller;
estimating, with the controller, an orientation of at least one light source relative to the automobile using a Convolutional Neural Network technique to determine the location of the at least one light source within an image by:
identifying corresponding points between known shapes and the at least one light source;
computing a homography matrix of the at least one light source; and
decomposing the homography matrix to determine an angle of orientation of the at least one light source;

classifying, with the controller, the at least one light source as one of relevant and irrelevant; and
when the at least one light source is classified as relevant, sending information about the at least one light source to a planning module for the automobile.
