Abstract: 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.
