Abstract
This paper presents interactive techniques for visually annotating
independently moving objects in a video stream. Features in the video
are automatically tracked and grouped in an off-line preprocess that
enables later interactive manipulation and annotation. Examples of
such annotations include speech and thought balloons, video graffiti,
hyperlinks, and path arrows. Our system also employs a
direct-manipulation interface for random frame access using spatial
constraints. This annotation interface can be employed in a variety
of applications including surveillance, film and video editing, visual
tagging, and authoring rich media such as hyperlinked video.
