Abstract
Abstract A method for synthesizing multiple intermediate view images from a pair of planostereoscopic source images. The source images have different perspective views which are spaced apart in a horizontal plane. Control points are defined at corresponding locations in the source images, and each control point includes position and color information. Intermediate images are created as transformations of the source images by "morphing" from one source image to the other using position and color information from each of the corresponding locations. In a panoramagram embodiment, the intermediate images and the source images are then interdigitated to create a single output image with a continuum of views ranging from one source image to the other source image.
