ABSTRACT:
A method of identifying an object from a digitized image is disclosed. The method is particularly applicable to the classification of ships. The digitized image of an unknown ship is represented as a set of vertical vectors. The vertical vectors are normalized and then compared to a library containing normalized digitized images of known ships. The unknown ship is thereby identified as being similar to the known ship corresponding to the library image most closely matching the image of the unknown ship.
