This paper describes a method of using elliptical features in model matching that forms the basis of a system for vehicle detection and classification. The novelty of the system is the employment of an algorithm that utilizes both line and ellipse features simultaneously. The baseline algorithm has been successfully used in images, which contain straight line features, to find a discrete correspondence between an object model and image features and to determine the pose of the object in the image relative to the camera. This research enhances the baseline algorithm by using elliptical image features to recognize circular objects in a model. Elliptical features show many desired properties in recognition. Utilizing these features not only increases the confidence level of detection and classification, but also provides the system with a good initial pose for a more robust performance.
