摘 要：In this thesis we describe two projects based on image warping that give photographerssome of the same control over spatial layout that painters have always had. The first is a technique to minimize distortion in a wide-angle image. Any projection of a 3D scene onto a plane unavoidably results in distortion; current methods either bend straight lines in the scene or locally distort the shapes of scene objects.
