The problems of speech recognition and orthographic word correction have been greatly mitigated by the use of dynamic programming techniques for finding the distance between two finite sequences. This paper extends the technique into two dimensions, and presents an algorithm for finding the distance between two finite areas. Applications of the algorithm are suggested.
