The technique relies on geometric image interpolation, known as "morphing" in the graphicscommunity, to produce intermediate images. Although morphing techniquescurrently enjoy widespread use, their theoretical validityhas not been established. In particular, does 2D interpolation of two viewsof the same scene produce a sequence of physically valid in-between views ofthat scene?Surprisingly, the answer is yes, providing the images first undergo a simplerectification procedure and certain assumptions about visibility and theprojection process are satisfied.The view synthesis work described here uses automated stereo techniques todetermine image correspondences.
