| A large number of previously recorded videos
cannot be directly visualized on mobile devices like PDAs or
mobile phones due to an inappropriate screen resolution of their
displays. Transcoding can be used to change the resolution,
however, the usual transcoding algorithms have problems
preserving the semantic content. For instance, superimposed text
is unreadable if the character size drops below a certain value.
In this paper, we present a novel adaptation algorithm to scale
and crop videos while preserving their semantic content. Semantic
features in a shot are combined to select a suitable region to be
presented in the adapted video. |
