Recently there has been a great deal of interest in ``image morphing'' techniques for producing smooth transitions between images. These techniques combine 2D interpolations of image shape and color to create dramatic special effects that have appeared widely on television and in numerous films.

In this talk, I will discuss how 2D image morphing methods can be extended to synthesize 3D effects by exploiting basic principles of projective geometry. Towards this end, I will describe a new technique, called ``view morphing'', that is capable of creating physically correct camera viewpoint transitions between images. Using this technique, it is possible to modify the camera viewpoint of an image after it is taken. Because the method does not require knowledge of either 3D shape or camera viewpoint, it may be applied to paintings and photographs, as well as to rendered scenes. Several example morphs will be shown, including faces of a some local CS personalities.
