Web-Based Multimedia Editing

It should require a nearly complete rewrite of a
stand-alone multimedia editing program to make it
operational through a Web browser, since it involves a
very different environment and technique. We have
implemented two interactive, Web-based tools for
multimedia editing. One is for image matting. It is the
first image matting tool accessible through a Web
browser, and can extract a foreground with thin,
thread-like shapes. It begins to process inputs
immediately after the user has started to paint with a
brush roughly along the boundary between the foreground
and the background. The user can stop anywhere while
painting, and change the width of brush as needed to
help achieve good foreground quality. The result is
generally better or not worse than those done by some
other similar tools. The other is for video editing.
Many new functions for editing digital videos, such as
adding or mixing audios to a film, have been included.
The functions can be integrated into a multimedia blog
to enrich the sharing of multimedia contents.
