Claim 10:
11. A system for determining relevance of a light source to an automobile, comprising:
at least one camera adapted to capture images of light sources in proximity to the automobile;
a controller in communication with the at least one camera and adapted to receive captured images from the at least one camera;
the controller further adapted to estimate 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 when estimating the orientation of the at least one light source relative to the automobile and estimating widths and heights of the extracted elliptical areas by one of an elliptical Hough transform and weighted standard deviation of horizontal and vertical pixel coordinates using pixel luminance as weights when estimating the orientation of the at least one light source relative to the automobile, classify the at least one light source as one of relevant and irrelevant, and, when the at least one light source is classified as relevant, send information about the at least one light source to a planning module for the automobile.
