Abstract
A method of identifying an object from a digitized image is disclosed. One embodiment of the method is particularly applicable to the classification of ships and a second embodiment is particularly applicable to the classification of aircraft. The digitized image of an unknown object is represented as a set of vertical vectors or, in the second embodiment, a set of radial vectors. The vectors are normalized and then compared to a library containing normalized digitized images of known objects. The unknown object is thereby identified as being similar to the known object corresponding to the library image most closely matching the image of the unknown object.
