The hit-or-miss operator is used as the building block ofoptimal morphological restoration filters. Using the conditional expectation in a binary setting, filter design methodologies are given for general, maximum, and minimum noise environments, the latter two producing optimal thinning and thickening filters, respectively. Unions ofhit-or-miss transforms are expressed as canonical logical sums ofproducts. The final hit-or-miss templates are obtained by logic reduction.
