A developmental approach to dynamic scene understanding
Christian Balkenius, Birger Johansson · 2006
To accurately track a moving target despite delays in the visual processing, it is necessary to predict how the target will move in the future and to direct the gaze toward the anticipated location. We have addressed this problem within a simulated visual scene were a ball is dropped from a random location and subsequently bounces or rolls on different objects before it comes to rest. A developmental system has been designed that attempts to track the location of the ball as closely as possible despite a delay of 250 ms from the the visual input to the control of gaze. The system is an extension of an earlier model of gaze development (Balkenius and Johansson, 2005). A standard Kalman filter-based tracking framework is used that gradually develops a set of parallel
