摘要: A system that captures both whiteboard content and audio signals of a meeting using video camera records or transmits them in real-time. The Real-Time Whiteboard Capture pen strokes on whiteboards real time an off-the-shelf camera. Unlike many existing tools, the RTWCS does not instrument pens whiteboard. It analyzes sequence captured images time, classifies pixels into background, foreground objects (e.g., people front whiteboard), extracts newly written strokes. This allows to transmit contents very low bandwidth remote participants. Combined with other teleconferencing tools such as voice conference application sharing, becomes powerful tool share ideas during online meetings.
