Pele-Mele, a video communication system supporting a variable degree of engagement

摘要

Pele-Mele is a multi-party video communication system that supports a variable degree of engagement. It combines computer vision techniques with spatial and temporal filtering of the video streams and an original layout to support synchronous as well as asynchronous forms of communication ranging from casual awareness to focused face-to-face interactions. This note presents the system's design concept and some of its implementation details.
