Fixation Simplifies 3D Motion Estimation

Fixation is defined as holding the gaze direction towards the ized that the key for a computationally simple solution is same environmental point through time. It was proven in the in the selection of the appropriate representation for the past that fixation reduces the number of unknowns in passive dynamic imagery. Furthermore, active vision involves the visual navigation from five to four. In this paper, we show control of the degrees of freedom of image acquisition. In that fixation further simplifies 3D motion estimation because it motion related tasks this could mean the pursuing of a decouples the motion parameter space. We project the spherical moving object, the fixation on a stationary point, or even motion field in two latitudinal directions with respect to two keeping the gaze aligned with the heading direction. different poles of the image sphere. The first projection enables In this study, we are interested in the computational the computation of the longitude of the translation direction advantages of fixation on an environmental point. There and the torsion. The second projection gives the angle between
