This paper describes a method of precisely aligning two digitized images prior to a point-by-point comparison of the images. Histogram specification to a reference is used to align the images in the photometric axis. A novel method of estimating the location of the cross-correlation peak using a parabolic surface is given. The accuracy of spatial registration using this method is 1/16 pixel. A hardware implementation and error analysis is also included.
