The channel anamorphosis
JAMES L. HUNT · Journal of Mathematics and the Arts · 2009
The history and description of the channel anamorphosis is briefly discussed along with several possible distortions of the observed image. The amelioration of these distortions as well as the mathematical methods to construct ‘exact’ anamorphoses which are distortion-free at finite viewing distances are discussed. Two well-known anamorphoses are analysed using the mathematical formalism. Finally, three- and five-image channel anamorphoses are briefly discussed.
