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.
