Abstract :
In this paper, detection and estimation of rotational motion in the 3-D Gabor domain are investigated. By extending frequency domain methods to the joint spatiotemporal/spatio-temporal-frequency (st/stf) analysis framework, we propose a technique to estimate multiple localized rotational motions in image sequences. Based on a rotational motion model derived in the 3-D Gabor domain, an algorithm for estimating localized uniform rotational motions is constructed and discussed.
