Recent research on perceptual grouping is described with particular emphasis on identifying the level(s) at which grouping factors operate. Contrary to the classical view of grouping as an early, two-dimensional, image-based process, recent experimental results show that it is strongly influenced by phenomena related to perceptual constancy, such as binocular depth perception, lightness constan...

In conventional multicast communication, the source carries a single conversation with all destination nodes. If a node on the path to any destination becomes congested, the throughput to all destinations is reduced, thus treating some destination nodes unfairly. We consider a window-controlled multipoint connection and study the use of destination set grouping, where the destination set can be...
