Abstract:
A target image captured from a fisheye lens or other lens with known distortion parameters may be transformed to align it to a reference image. Corresponding features may be detected in the target image and the reference image. The features may be transformed to a spherical coordinate space. In the spherical space, images may be re-pointed or rotated in three dimensions to align all or a subset of the features of the target image to the corresponding features of the reference image. For example, in a sequence of images, background features of the target image in the spherical image space may be aligned to background features of the reference image in the spherical image space to compensate for camera motion while preserving foreground motion. An inverse transformation may then be applied to bring the images back into the original image space.

Claim (Index 24):
The method of  claim 22 , wherein the applying of the rotation further comprises:\n determining first three-dimensional Cartesian coordinates corresponding to the subset of the first spherical feature coordinates and second three-dimensional Cartesian coordinates corresponding to the subset of the second spherical feature coordinates; determining a first coordinate centroid of the first three-dimensional Cartesian coordinates and a second coordinate centroid of the second three-dimensional Cartesian coordinates; determining first translated coordinates as a difference between the first three-dimensional Cartesian coordinates and the first coordinate centroid, and second translated coordinates as a difference between the second three-dimensional Cartesian coordinates and the second coordinate centroid; determining products between each of the first translated coordinates and respective corresponding second translated coordinates; determining an accumulation matrix as a combination of the products; and applying a singular value decomposition to the accumulation matrix to determine a rotation matrix, the rotation matrix indicating the rotation to apply to the target image in the three-dimensional spherical space.
