Registration of Distorted Images

Abstract

An image registration method involves computing horizontal and vertical integral projection vectors for first and second distorted or partially distorted images or distortion-corrected images, or both. The images are registered by applying a translation, rotation and/or scale factor estimation between the first and second images on the horizontal and vertical integral projection vectors.

What is claimed is: 
     
         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;   applying at least an approximation of an inverse distortion function to the horizontal and vertical integral projection vectors of the first and second distorted or partially distorted images to generate distorted horizontal and vertical integral projection vectors;   registering the first and second distorted or partially distorted images, including applying a displacement, rotation or scale factor estimation, or combinations thereof, between the first and second images on the distorted horizontal and vertical integral projection vectors; and   performing a further action using the registered first and second distorted or partially distorted images.
