Claim One:
1. An image registration method, comprising: acquiring first and second distorted or partially distorted images of scenes that each include a first object; computing horizontal and vertical integral projection vectors for the first and second distorted or partially distorted images or distortion-corrected images, or both; registering the first and second distorted or partially distorted images, or the distortion-corrected images, or both, including applying a scale factor estimation between the first and second images on the horizontal and vertical integral projection vectors, including: resampling at least a portion of the first distorted or partially distorted image with multiple different resampling factors over a range of resampling factors to generate multiple resampled integral projection vectors; computing for each of the different resampling factors an absolute sum of differences, or sum of squares, between the resampled integral projection vectors of the first image and corresponding integral projection vectors of the second image; and determining the scaling factor between the first and second distorted or partially distorted images, including finding the resampling factor that corresponds to the minimum value of the absolute sums over the range of resampling factors; and performing a further action using the registered first and second distorted or partially distorted images or the corrected images, or both.
