For real-time location, a new algorithm is proposed which uses a simple but efficient description of the image of any isolated object. This description is a small set of points, one being the barycenter of the contour of the image object, and the others being the intersection points of the contour and of a circle centered at the barycenter. Two characteristic vectors are calculated and used for the determination of the object orientation and of the face of a flat object. Several methods are given to obtain the intersection points. Some details of the implementation of the algorithm and real-time experimental results are also mentioned.
