1. A method of processing data at a local station to produce data representing images of participants at remote stations, comprising the steps of: receiving at the local station data representing the images of the participants at the remote stations and data indicating facings of the participants at the remote stations with respect to cameras at the remote stations; processing at the local station the data representing the images of the participants at the remote stations to isolate the participant in the image from image background; merging, at the local station, data representing the processed images of the participants at the remote stations to generate data representing an output image in which a first processed participant image appears to partially overlay a second processed participant image and in which the first processed participant image appears in the output image horizontally translated relative to the second processed participant image by a distance determined in response to the data indicating the facings of the first and second participants; and providing the data representing the output image at an output of the local station suitable for coupling to a display device.
