An image matching method that uses corners of objects, rather than their edges, to determine if the objects match. Corner locations are obtained by finding changes of curvature in the edge boundaries of the image. The corners of a reference image are used to create a distance array, which is used as a look-up table to determine how far each corner of a test array is from a corresponding corner of the reference array. A close corner-to-corner relationship indicates a good match.
