Abstract
Subpixel scene registration is useful for certain image processing applications. The scene shifts do not necessarily have to be integer shifts. In this paper, we present an image registration approach that is based on the wavelet decomposition and the Fitts correlation algorithm. The original Fitts algorithm is ideal for small-scale translations. A successful image-based tracker using Fitts correlation for position measurement will require additional modifications to the original algorithm to enable it to perform the small-scale translations. We used a wavelet transform to preprocess the images before performing scene registration.
