Abstract: We present a computationally simple and fully automatic method for creating virtual views of a scene by interpolating between three images obtained from different viewpoints. The technique is intended to give an immersive experience and a sense of viewing a real environment. The method uses correspondence points identified in the primary images. The matching of corresponding locations in the images is edge-based and relies on the automatic extraction of suitable epipolar geometries. The resulting edge correspondences are then interpolated and used in an efficient morphing algorithm that operates one scan- line at a time to perform image synthesis.
