Six different algorithms (Single Differencing, Double Differencing, Linear Interpolated Differencing, Parabolic Interpolated Differencing, Spatial Differencing and Spatial Filtering) are investigated to judge their ability to track subpixel targets in moving background and additive noise. This investigation used a set of computer generated imagery for the targets, background and the additive noise. Based on this extensive simulation study, guidelines are provided about the selection of the algorithms.
