Active Visualization

Our research attempts to exploit foveated visual geometries in visualization applications on the internet. The following Java-based demo illustrates such geometries. We use a new foveation technique based on wavelets. Haar wavelets is used for the present demo. Note that the current demo is implemented in Java and is slow! Its main purpose is to illustrate foveation using wavelets and the possible bandwidth reduction that can be achieved.

Description of Foveated Image Server Demo

The user is presented with an initially foveated image. The user obtains further images by clicking at any point in the image, and a new foveated image centered at the clicked point will be displayed. The user can also control the size of the foveal region. Specifying larger foveal region will improve the quality of the overall image but requires more transmitted data (this is indicated in a readout).
