FREQUENCY-DOMAIN ANALYSIS OF ROTATIONAL MOTION

The consideration of translational motion in the frequency domain has rendered valuable service in many applications, such as television sig nal analysis, motion estimation, image registration, and visual percep tion studies. This work presents rotational motion in the frequency do main, developing theoretical results parallel to those relative to tra nslations. The analysis can support the extension of frequency-domain- based approaches to specific applications concerning rotations, an ope ration successfully carried out by recent image registration works..
