Foveation Theory

What is foveation?

Here is a uniform image:
.
Here is a foveation of the image at the leftmost face:
.
It is of course, possible to foveate in a more general sense. Here is the image foveated at two gaze points:.


Formulation

We are interested in the mathematical formulation of foveation. Click here for a preliminary report that will appear in the 1997 ACM Symposium on Computational Geometry.

Foveation Demo

We wrote a little java demo to illustrate the kind of bandwidth reduction that can be obtained by foveation. Note: the demo is slow in part because the reconstruction is done by an applet.
