Chalkboard and Marker Regions
When recording a classroom lecture, it is useful to capture
the writing on the board for processing by applications.
To provide more useful information for applications, we
group together strokes based on the meaning of the writing.
However, it is currently not possible to automatically
obtain this meaning, or general semantic information automatically.
Instead we rely on the structure of writing to
approximate regions of the board, where each region represents
a single thought or idea. These regions provide an
abstraction of the board that can be used in several applications,
such as a note taker, a lecture indexing program,
an automatic video editor, and a program for creating multimedia
presentations.
