ubiquitous and will exist for foreseeable future, but its content is hard to archive and share. While digital cameras
can be used to capture whiteboard content, the image is usually taken from an
angle, contains irrelevant information, and has shadows.
We have developed an intelligent and automatic technique to reproduce the whiteboard content as a crisp and faithful image which can be archived or shared with others. Furthermore, we cover other scenarios such as scanning the whiteboard with a low-resolution PC camera and, by adding a microphone, streaming the meeting to remote participants and archiving it for ulterior efficient browsing.
The technologies we
have been developing allow information workers to use whiteboard in a more
effective way, yet without increasing their burden of adapting their behavior to
new technologies as other commercial systems do.
Depending on different scenarios, we provide four systems:
Whiteboard Streaming (Live Whiteboard): Stream whiteboard contents to remote party for annotation and real-time feedback. The whiteboard contents captured by a video camera have been processed in real time to remove foreground moving objects and to enhance image quality.
