This work deals with the view synthesis problem, i.e., how to generate snapshots of a scene taken from a "virtual" viewpoint different from all the viewpoints of the real views. Starting from uncalibrated reference images, the geometry of the scene is recovered by means of the relative affine structure. This information is used to extrapolate novel views using planar warping plus parallax correction. The contributions of this paper are two-fold. First we introduce an automatic method for specifying the virtual viewpoint based on the replication of the epipolar geometry linking two reference views. Second, we presents a method for generating synthetic views of a soccer ground starting from a single uncalibrated image. Experimental results using real images are shown.
