Claim One:
1. A method of producing an optimized set of values for a plurality of filter parameters, said method comprising: obtaining a captured representation of a reference pattern; based on the captured representation, obtaining a pattern for matching; performing a filtering operation that is based on a set of values for the plurality of filter parameters, including performing said filtering operation on the captured representation to produce a filtered representation; evaluating at least one difference between the filtered representation and the pattern for matching; based on a result of said evaluating, modifying at least one among the set of values; and performing at least one further iteration of a sequence of said performing a filtering operation, said evaluating, and said modifying such that: said set of values in each further iteration of said performing a filtering operation is the set of values as modified in the previous iteration of the sequence, and said filtered representation in each iteration of said evaluating is the filtered representation produced in the current iteration of the sequence, and said result in each iteration of said modifying is the result of said evaluating in the current iteration of the sequence.
