Knowing 36 Chapter 2 initial conditions, any subsequent observation of the pendulum is redundant. Realistic visual tracking problems are more like observing a pendulum oscillating in a turbulent airflow. The mean behaviour of the pendulum may be explained as deterministic simple harmonic motion, but the airflow drives the motion with random external forces. 3) where X and X are the first and second temporal derivatives of X and w is a random disturbance. Thus the value of initial conditions weaken over time, as the motion of the pendulum is progressively perturbed away from the ideal deterministic motion.

1992). g. (Adjoudani and Benoit, 1995). , 1994). The technique of rotoscoping allows film-makers to transfer a complex object from one image sequence to another. This can be done automatically using blue-screening (Smith, 1996) if the object can be filmed against a specially prepared background. Introduction 23 Computer-aided techniques for object segmentation are also of great interest for augmented reality systems, which attach computer-generated imagery to real scenes. , 1993; Wloka and Anderson, 1995) to solve this problem, but they are inaccurate and cumbersome.

R Thumb open: object follows hand translating and rotating. 16: A hand tracked in real time by a video camera acts as a three-dimensional mouse. Moving the thumb towards the hand acts as an "indexing" gesture, equivalent to lifting a conventional mouse off the desk to reposition it without moving the pointer. ) Introduction 21 Bibliographic notes Despite enormous research effort, the pinnacle of which is represented by (Marr, 1982), the goal of defining general low-level processes for vision has proved obstinate and elusive.
