Abstract
A technique for compensating for egomotion of the camera used to record a pair of two-dimensional views of a scene when the pair of images is to be used to provide a three dimensional representation of the scene. The technique involves comparing histograms of the intensity levels of pixels of corresponding epipolar lines in the pair of images for assumed amounts of egomotion to identify the amount that results in the smallest total of the sums of squared differences of the histograms.
