An efficient method for designing optimal 2-D FIR digital filters with finite wordlength
C. Charalambous, M.F. Abusharkh · 1991
A general algorithm for designing finite impulse response (FIR) linear-phase and finite-wordlength 2-D digital filters is presented. The branch and bound technique in conjunction with the I. Barrodale and C. Philips (BP) linear minimax algorithm (1974) is used to solve the discrete variable problem. An approach has been developed which has the important property that once the root node is generated the rest of the subproblems can be solved very efficiently. In some cases it is not even necessary to solve the subproblem to realize that one can stop further branching.>
