Abstract
Success of visual tracking typically relies on the ability to process visual information sufficiently fast. Often a dynamic system model of target motion is used to estimate the target location within the image and a region of interest (ROI) is used to reduce the amount of image data processing. This has proven effective, provided the ROI is sufficiently large to detect the target and sufficiently small to be processed quick enough. Here we formally consider the size of the ROI and the resolution of the ROI to ensure that tracking is stable. Dynamic system formulation of visual tracking usually requires specification of the dynamics of the target. We analyze motions which can be described by linear time-invariant dynamical systems (although the image motion may be highly non-linear). One can successfully analyze the required ROI size and resolution to ensure stable tracking.
