Abstract
A method for automatically registering an image pair having a common coverage area, wherein a pair of image data sets, each representing an image of an image pair, are processed to generate initial dewarping coefficients for the image data sets. The translational offset between the images is estimated using a phase correlation process. Next, the common coverage area of the data image sets is determined by finding the vertices defining the limits of the common coverage area. Conjugate point pairs are extracted from the common coverage area by defining a series of block and subblock grids and defining the center point of the grid as a conjugate point location. The determined conjugate point sets are used to generate geometrically corrected registered dewarping coefficients and the image data sets are resampled using the registered dewarping coefficients to generate a registered image pair.
