Abstract :
New recursive and nonrecursive methods to evaluate the impulse response h(m, n) of a first-order 2-D filter are derived. New bounds for |h(m, n)| and ¿¿m=0 ¿¿n=0 |h(m, n)| are also presented, with the latter bound finding applicability in evaluating the error due to internal product quantisation.
