4. THE “NEW” MEDIA
To the author, the future of content-based analysis as a research field
depends highly upon the existence of “new” content that is not express-
ible through traditional media. Video and movies are powerful presen-
tation tools and art forms. This topic advocates a movement toward
video as a deeper language of communication. Let us give one example
of a content-based video processing that expresses a narrative concept
in a novel manner.
The movie,
The Matrix
[Wachowski and Wachowski, 1999], is a re-
markable breakthrough in the video processing, because a technique of
video processing actually conceptualizes a subjective reality. The notion
of a moment of freezing time due to the subjective importance of an
event is implemented through simultaneous video shot through a linear
array of cameras on top of a synthetic background. For an event of
extreme subjective important (i.e., when a bullet is shot), the notion
of time also becomes subjectively important within the movie. Since
simultaneous views of the same subject are taken, simultaneous frames
from different cameras can be assembled into a series so that the viewing
perspective moves in space, but not in time. This notion of subjective
time is not represented by the subject matter of the movie, but rather
by a specific technique of video processing.
In truth, we do not know where these technologies will lead or what
type of video content will drive the video processing into a mainstream
mode of communication. However, we do know that society and com-
munication are intertwined: in the course of human events, people have
embraced any technology that aids communication. Although we are
unsure of the exact nature of the “new” media, we expect the technolo-
gies in this topic and other future media-based technologies to enable
new and expressive forms of communication.
