Abstract
An apparatus and method relating to use of a physical writing surface () during a videoconference or presentation. Snapshots of a whiteboard () are identified by applying a difference measure to the video data (e.g., as a way of comparing frames at different times). Audio captured by a microphone may be processed to generate textual data, wherein a portion of the textual data is associated with each snapshot. The writing surface may be identified (enrolled) using gestures. Image processing techniques may be used to transform views of a writing surface.
