Abstract:
It is a remote Sketching system based on camera-projector.
The captured images are displayed on the projector.
It is applied in Teleconferencing and remote Education.
What’s Tele-Graffiti?
• Tele-Graffiti is a system allowing two or more users to communicate remotely with hand drawn sketches.
• A person writing at one site is captured using a video camera, transmitted to the other end.
• Design and implementation of the system
Paper Detection:
• Camera sees the paper and projected image from the previous step.
• Paper detection algorithm had been developed.
(a)The paper is bounded by four edges.
(b)Edges are removed .
©Ambiguous is resolved by the asymmetry between top and bottom of clip board.
Architecture:
Procedure:
• We can place the writing pad any where on the desk.
• Inputs on the pad are appear simultaneously at both ends.
• The camera tracks the edges of paper.
Advantages:
• Multiple users can share the single piece of paper.
• Distance Education will be benefited as students and the teacher.
• Filling web forms.
• It serve as a substitute to Internet Chat.
Conclusion:
• Many innovative reforms and technologies have developed in communication system.
• Many advantages like Tele Conference and Remote Education.
• We can reduce the size of the system and to light weight the systems.
