The invention provides an apparatus, and related method, for providing a procedure to analyze images based on two-dimensional shape primitives. In the procedure, an object representation is created automatically from an image and then this representation is applied to another image for the purpose of object recognition. The features used for the representation are the two type of two-dimensional shape primitives: local line segments and vertices. Furthermore, the creation of object representations is extended to sequences of images, which is especially needed for complex scenes in which, for example, the object is presented in front of a structured background.
