A method for determining whether a perceived target is acceptably close to a model target. The perceived target is first segmented using a relaxation based procedure. Structural features from the perceived target are extracted by producing a compact one-dimensional description of the perceived target\s boundary. Said structural features are classified by using string-to-string matching, wherein one of two symbolic strings is a representation of the compact one-dimensional description of the boundary of the perceived target, and the other of said two symbolic strings is a pre-stored representation of the model target. The string-to-string matching entails measuring the distance between the two strings based upon deletion, insertion, and substitution of symbols from one string to the other. Performing the string-to-string matching measures how closely local structural features of the perceived target resemble local structural features of the model target.
