In this paper, even-order-difference fairing (EOD-fairing) of point-sequenc
e curve (PS-curve) is analyzed using a discrete Fourier transform filter (D
FT-filter). It is shown that EOD-fairing of a reflection-padded PS-curve is
equivalent to DFT-filtering, and a DFT-filter corresponding to the EOD-fai
ring operation is derived. Based on the concept of filtering measure, a met
hod of determining an "optimal" damping factor for EOD-fairing is proposed,
and then the validity of the proposed method is demonstrated via experimen
tal tests. (C) 2000 Elsevier Science Ltd. All rights reserved.
