Abstract
A method and system are disclosed for differential distortion correction for use in the three-dimensional (3D) projection of film-based or digital images. A compensation transform determined based on distortion information can be applied to image data to compensate for distortions in stereoscopic images for 3D projection. Different approaches can be used for obtaining the compensation transform.
