| Abstract: | This paper proposes an algorithm for active 3 D motion estimation involving activities of fixation and tracking through camera rotation. This method shows that an active observer with the ability to control its gaze and keep an environmental feature stationary on its image plane can transform some ill posed problems into well posed problems and solve problems of motion estimation,egomotion recovery,estimation of time to collision very efficiently due to reducing dimensions and the numbers of motion parameters,and avoiding complicated computation. |

| Keywords: | active 3 D motion estimation normal flow patterns active monocular observer time to collision |
