Close relationships exist between these various filters, and through understanding these relationships we can, along with gaining a better understanding of the principles behind the filters, approximate or replace one filter by another and reduce the computing complexity required to compute it.<\/jats:p><jats:p>The relationships between these filters have been explored on a one\u2010by\u2010one basis in the past, but in this paper a systematic assessment is made of the relationships between nine kinds of optimum restoration filters.
