Abstract :
A new method for videoconferencing using the concept of spatially varying sensing is introduced. Various techniques are discussed for combining information obtained from multiple points-of-interest (foveae) in an image. A fovea can be used to follow a moving object of interest as well. A fast videoconferencing prototype for desktop computers is also described
