This paper describes a robust technique for determining the best magnification to zoom in onto a target object while it is still at a long range. This would aid the recognition stage for a more accurate registration of a target object. The zoom process is modelled on the expected signal from the object and the background. The variance in a region of interest is shown to be a SNR indicator for the optimal zoom.
