Abstract
Analytical approximations of translational subpixel shifts in both signal and image registrations are derived by setting the derivatives of a normalized cross correlation function to zero and solving them. Without the need of iterative searching, this methods achieves a complexity of only O (mn), given an image size of m × n. Without the need to upsample, computation memory is also saved. Tests using simulated signals and images show good results.
