22. The method of claim 18, wherein only the next closest pixel image I** is weighted causing the next closest pixel image I** to become the next closest pixel template T**.
18. The method of claim 17, wherein the recognition enhancement of a particular pixel image I.sub.j with respect to a particular pixel version s.sub.i involves maximizing the minimum recognition margin between the primary comparison C* and the maximum secondary comparison C** which form the selected pair of identified comparisons C* and C** for the pixel version s.sub.i, in the general relationship: EQU maximize M=min[C*-max(C**)] where M is the recognition margin between C* and C**, C* is the primary comparison for the template T* which is the closest template in the library to the particular pixel version s.sub.i, and C** is the secondary comparison for the template T** which is the second closest template in the library to the pixel version s.sub.i.
