Abstract
A method and target detector for detecting targets. A number of bright pixels are identified in an image. Each of the number of bright pixels belongs to a line detected in the image in which the line represents a candidate for a target. A number of feature vectors are identified for the number of bright pixels in the image. Each of the number of feature vectors is classified as one of a target vector representing the target and a clutter vector representing clutter.
