A Study on the Role of Fixation and Tracking in Visual Motion Analysis
关于视觉运动分析中凝视与跟踪作用的研究

This paper proposes an algorithm for fixation and tracking and gaze control through camera rotation. An active observer with ability to control its gaze and keep an environmental feature stationary on its image plane can thus transform some ill posed problems into well posed problems. Problems of motion estimation, egomotion recovery, and estimation of time to collision can be solved very efficiently due to reduced dimensions, less motion parameters, and absence of complicated computation.
