Claim 5:
6. 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 connected pixels corresponding to critical colors and extracting elliptical areas of the critical colors;
estimating, with the controller, widths and heights of the extracted elliptical areas;
filtering, with the controller, the estimated widths and heights of the extracted elliptical areas to reduce noise and remove outliers;
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.
