Resolution vs. Tracking error: Zoom as a gain controller
During tracking, lens zoom acts as a gain between scene dynamics and fixation errors, providing a trade-off between maximising resolution and minimising tracking error. Using a linear Kalman filter model, it is shown that when image measurement error scales with focal length, the filter is invariant...
